Good afternoon! One lamp may be enough for the light (it's hard to manage with such a volume, but soft light will suffice), the filter should fit (it's just a regular backpack, right?), for such a volume, a foam filter may not be necessary (it would have been possible to order a jar with a compartment at the back for the sump, like those from Resun, Boyu, etc., where both the foam filter and algae scrubber and heater and many other useful things could fit, but which are visually unappealing). If you do get a foam filter, it's better if the pump is not located in the aquarium regarding "live sand" - I don't really believe in it, so I would opt for dry sand (with the price difference, you could buy bacteria for starting, or not buy them) and good live rocks.

Frederick

By the way, here is wonderful sand. You should have about 4 kg (dry) enough.

Holly

The backpack-type filter has "guides" for replaceable cartridges. I'm not sure if it will effectively clean everything. I didn't think that watts per liter would be sufficient; I read that more is needed. Will such a pump be enough for the initial period? Also, I have a question about the ATI and AquaMedic 24W actinic lamps. I'm leaning more towards ATI, but I haven't dealt with anything like this before, so I'm asking for advice.

Lindsay

I have about 2 watts per liter and I'm struggling with unwanted growths, I think it's due to excess light, although... Is the pump just available or will it be purchased? If buying, it's better to get a good one right away—it will be cheaper (although Atman is good for diluting salt), something like that or weaker (there will also be flow from the backpack and from the foam). I don't know about the lamps on the site, but I got an ATI for myself.

Mark

Yes, I already have a pump - a new one is lying around unused... later I want to use it for mixing salt. I was thinking of getting a Coral Nano later, but it's all quite expensive at once. There are options for 900 and 1600 l/h - which one is better? Will it create a "washing machine" effect in the aquarium? And I wanted to ask about the fish, what can I expect in this aquarium? Well, besides the usual two clownfish, which I admit I want... I understand I could also have a small goby and that's it? I want the aquarium to not be overloaded with inhabitants. Thank you for the answers.

Meghan

For starters, that might be enough (but not for long). As for the fish, besides fish, a couple of shrimp, hermit crabs, strombus, etc., the activity will be such that freshwater fish won't even dream of it.

John3187

Before installing the external backpack filter, check its operation after a power outage. Just in case.

Angela7060

I checked the filter. It turns on... more precisely, we have voltage fluctuations, so I installed a differential relay or whatever it's called (because there was a case where the equipment burned out). It disconnects the supply at 260 volts and after the voltage drops, it counts 10 seconds and turns back on. So the filter works fine. As for the pump, I still don't understand if 1600 is a lot for 45 liters or not.

Noah1632

The best answer to this question will come from those who have had the opportunity to see the operation of these pumps at such volumes (in my opinion, 900 should be enough, considering the backpack and the foam, but I could be wrong), and the panoramic shape of the aquarium should also be taken into account.

Rita

There was a question about the lamps. I ordered one, but which one should I take as a second if you say that 1 watt per liter is enough? I understood that the San-San lamps that come with the fixture are not very good.

Debra8438

For the time being, the San San lamps will do, they just burn out quickly.

Lori4746

I'm digging and digging but still haven't found hanging skimmers for my aquarium. Maybe someone can suggest something, ones that can be found here or through eBay?

Troy8808

If everything is fine with the hands, you can build something like this (from an aquarium for grains, bottles, and other very expensive components).

Natasha

And what if I want to buy a reliable hanging pen? But, unfortunately, I can't find it anywhere.

Lee425

Can anyone recommend a good hanging skimmer?

Amy

Look for Naniki Deltak or Tunze, they are basically new and not the cheapest, but maybe someone will sell them on the forum... But in general, you can keep such a large tank with replacements, it's not the most critical issue. As for the light, it's fine, more than enough. Regarding the flow, I think one Coralife 900 will be sufficient. If needed, you can add another pump for 300 liters, like an Eheim. As for fish: as mentioned earlier, clowns are good, you can also have chromis (but it's a matter of taste), and there are plenty of other small fish... Browse through catalogs or choose directly in the store, but I wouldn't stock too many fish (no more than 3-4).

Loretta5483

The following question arose: is 5 kg of live rock too little for such a volume?

Ryan

I have a 35x35 cm aquarium with 5 kg of live rocks; you can see what it looks like in my.

Selena4467

Are marine aquarium enthusiasts concerned about this salinity meter? I salted the tank almost a week ago and I'm worried about the salinity. This device shows 1.022. I forgot to add - I measured it at 25-26 degrees. Is there a significant difference at 26?

Kathryn514

A normal hydrometer, I also use one like that (you can check it by comparing the readings with someone else's refractometer or it should show zero in distillate). If it is slightly off somewhere, it's not as scary as salinity fluctuations (water added at the wrong time, sides during replacement). Thermometers also don't always tell the truth (the most honest ones seem to be mercury). I keep it at 1.024.

Jennifer9100

How much salt do you put per liter?

Michael5242

I put 40 grams of Tetra per liter (approximately).

Kristin

The hydrometer is good, I have the same one, no complaints about it. Before that, I had a dial one, it lied a lot, had to throw it away. 40 grams per liter is a bit too much, 36-37 grams is just right.

Michelle1505

Odessa, Well, scales can also have different levels of "honesty."

Johnny

I ordered scales with 0.01 precision for 300 grams from China. The total with shipping was 70. Can someone tell me if I need algae for my aquarium right now?

Andrew7823

Who can advise on the use of such products? Are they worth the money? And

Mario

In connection with the surge of responses, I will ask a bit about something else to avoid creating topics in other sections. M.A. (marine aquarium) These are hydroids, and how to deal with them? I couldn't find anything on the forum, but I read that deworming tablets in very minimal dosage help. Are there other methods? (Mechanical removal by other marine enthusiasts in the thread did not yield results.) I am thinking of setting up a 20L quarantine tank to carefully eliminate the pests—fortunately, the rock they settled on is only the size of my palm. There are no hydroids on the other rocks.

Monica

I corrected the post. I found something that might still be useful for someone about hydroids and control: On our forum, there were 2 suggestions: leave it as it is - they will disappear on their own, and mechanical cleaning. I will post the topic on the logo using the deworming medication later - I can't find it for now.

Chad231

I found a small brittle star on a stone that I want to remove for "processing." Can you advise me on how to take it off without damaging it? It has been crawling only on this stone for three days and hasn't been seen anywhere else. At night, it also sits on the stone and eats something.

Stephanie9175

Tear it off the stone with your hands, and that's it.

Danielle8118

Does anyone happen to have a small amount of S.R.K. (dry reef rocks)? I need some to create a slope, but no one wants to deal with small batches. I need 3-4 rocks the size of a fist.

Robert5335

Maybe someone can tell me what kind of creature has appeared in the J.K. (living stones)? It looks like a fan palm, but the "rays" are not as dense. The camera doesn't allow me to take a closer photo.

Jennifer7159

it turns out to be some kind of blog, not a forum

Kimberly2102

Don't take it to heart. It's mid-autumn, a general apathy, and only scandalous topics can stir people up, and even then, only for a short time. In the photo, it's most likely a fan worm; there are a lot of species. To be more precise, a macro-format photo is needed.

Robert1845

Anton, don't stress yourself out, or you'll go crazy if you try to identify every little bug and every "chebryak." That's what live rocks are for, to let all sorts of creatures come out. It's only when you have a worm from the live rock that comes out at 15 cm that you should raise the alarm.

Kimberly2102

Thank you, you calmed me down. I would like to see you right after the bland. You study J.K. (living stones) for 2 hours every day and it's still interesting. Like in the joke, "... and then they filled the pool with water..."

Robert1845

Hydroids must be completely destroyed, even to the point of throwing out the rock. If this stuff spreads, you won't be able to get rid of it by any means. It even grows on silicone. One of my acquaintances completely restarted a 700-liter aquarium because of them.

Craig7302

Could you tell me if any tests are needed for a beginner sailor? kH, phosphates, nitrates? And what would you recommend? I understand that good options are salifert and TM? P.S. The start was on October 28.

Karen81

Needed: for nitrites/nitrates, phosphates, silicates, calcium, magnesium, KH. It is better to use electronic devices for measuring pH. Ideally, you need 2 devices: a pH meter to measure pH in the aquarium and a pH controller for the calcium reactor. Salifert or Tropic Marin - choose whichever name you prefer. Both manufacturers have accurate tests. Tropic Marin boxes are smaller and will take up less space. Pay attention to the expiration date of the tests.

Jeffery7866

Not a fact. With such photo quality and a rich imagination, you could fit a couple dozen more thriving creatures under "THIS."

Christine

I checked with the quality ones online - they match mine. I think these are hydroids.

Katie4842

I had a lot of hydroids on the fresh live rocks, but they somehow disappeared over time.

Helen

Sorry, I missed that. Yes, 5 cm is enough. In working mode, the level will rise from the edge of the shaft by approximately 1.5 cm, and the remaining 3.5 cm will be sufficient for safety. I recommend installing the valve on the supply rather than the drain like many do; it will be easier to adjust the drain based on noise and the speed of the draining water, and it will also be safer.

Jeffrey6189

Thank you for the answers. Is it 5 cm from the edge of the comb or from the glass to which the comb will be attached? When placing the tap on the inlet, will the pump's performance decrease? I feel like 2300 is just barely enough. Besides NewJet, I'm also considering the Hydor Seltz L30, but according to the graph, it pumps less. How much flow rate is generally needed in volumes per hour, 4? And another question has come up - is it worth making the sump almost the entire length, or should I make a compartment for electricity and stuff in the remaining space?

Charles5941

From the glass to which the comb will be attached. It won't fall. The NewJet 2300 pumps will be sufficient; with all losses, the performance will be approximately 1200-1500 l/h, which in your case is 5-7 volumes/h. The more water in the system, the more stable it is. Decide for yourself and do everything so that it will be convenient to service the equipment in the future. It's better to determine the equipment right away and plan what and where it will be placed.

Travis572

What do you mean by "close to what?" The power of the feed pump is greatly exaggerated. Previously, the feed pump somewhat took on the duties of the flow pumps. Now it is primarily needed to supply water to the skimmer. I have an Eheim 1250 (1200 l/h) pump for 200 liters, and everything is great. In your case, 1700 will be just right. The more powerful the pump, the more noise it makes.

Angela6489

at maximum performance. According to the schedule, the supply will pump about 1000 liters per hour if there are 300-350 liters of water in the system - is that enough?

Joseph9203

Take the NewJet 2300.

Nicholas2252

I agree with Denis on 350 liters, better than 2300, especially since they are adjustable.

Monica

You need to consider not only the pump's performance but also the height of water delivery (for me, this is a crucial question). There are pumps with a capacity of 3000 liters per hour, but with a lift height of 1.5 meters, and there are pumps with a capacity of 2000 liters per hour, but with a lift height of 2.5 meters. The one with the higher lift is better. Comparing different pumps with Eheim...

David4089

Post number 47 We have already discussed...

Samuel6138

Offtopic missed it.

Omar3497

Another important question before ordering the aquarium. Three options: 1) make only one 32 drain pipe in the shaft (return with a hose behind the aquarium) 2) make a 32 drain + 20 return 3) maximize with a 32 drain + 25 emergency and 20 return I see that many have the first option and don't worry?

Danielle

Choose the first two options, but in my opinion, the second one is better.

Noah1632

since it's more compact, but here we need to calculate everything correctly regarding water supplies to avoid making an emergency situation

Andrew419

The emergency system is a wonderful thing. It is possible (and necessary) to calculate that the aquarium will take all the water from the sump. But the pump, skimmer, etc. will burn out... however, the emergency system will return everything back to the sump. I can't understand what the downsides of the emergency system are? Additional hole, space???

Lindsay

Option 1 or 2. I have the first one on all my aquariums. If there is no background, then the second one needs to be made. Why? If the sump is properly calculated, there is no need for it. The aquarium just needs to accept all the water from the section where the return pump is located. And if the drain is made correctly, it is practically impossible to clog it...

Christopher4108

Yes, the aquarium has accepted everything. The sump is empty. What will happen with the skimmer and the return pump? Sorry for being persistent, but I don't understand. They also didn't respond about the downsides of the emergency system.

Wendy8540

What will happen to them? Saw it - turned it off, so there was no talk about the downsides. As for the necessity of this device, everyone decides for themselves.

John3187

In the sense of "Saw"? What if there's no one at home? The return pump just burns out, shorts out, and voilà.

Antonio

Well, that's already extreme; are there examples, facts?

Kendra2262

Who said that the sump is empty? In the penny compartment, the water level hasn't even dropped. New Jet pumps, for example, have dry run protection. And once again - with a properly made and adjusted drain, it is practically impossible to clog it.

Tonya

No. A simple modeling of the situation.

Joseph9057

As far as I understand the operation of the drain and return pump, when the power goes out, the water level in the sump will drop to the overflow, and the sump should be designed to accommodate this volume of water. However, if the drain gets clogged, only compartment 7 in the diagram will be emptied, while water will remain in compartments 5 and 6. The skimmer will not be affected. Also, NJ pumps seem to be designed to prevent overheating when running dry.

Amy1672

Here is a rough sketch I made. However, I couldn't determine the necessary size of the hole in the shaft, as well as why a diameter of 43 mm is needed for a 32 mm pipe. Below is a photo of the proposed coupling and the sketch of the aqueduct: and the drawing Data: d1 = 32 mm d2 = 40 mm d3 = 1 1/4" Z1 = 17 mm Z2 = 0-26 mm B = 22 mm C = 26 mm D = 49 mm S = 50 mm Please advise on what the optimal dimensions of the shaft are, and also, according to the coupling drawing, with a size of d3 = 1 1/4", is a hole of 35 mm sufficient?

Mariah

Drill 40 and try to insert the fitting.

Tara2761

32 is the internal diameter of the pass-through coupling, and the external diameter is 42. I recommend drilling a hole with a diameter of 45. The size of the shaft is 20cm x 13cm, which is sufficient for drainage and supply. If there is only a drain in the shaft, the Durso will take up about 12cm x 6cm, so you can calculate the size of the shaft from this.
