• grams of salt per liter of osmosis

  • Joshua448

Aquarium enthusiasts, please advise on the correct ratio. I want to salt 30 liters for a water change, and I have kitchen scales... I remember there was a topic that mentioned about 32 grams per liter of RO water... my current salinity is 1.023, as indicated by the Serov float.

Each salt has a different concentration. Check the box. In TM about the reef, it's 34 grams per liter, I think.

AquaMedic 33-34 g/L

Tropic Marin, I poured it into a separate bag, so thank you, I think it won't make a difference with such a volume anyway, 33-34 degrees... I tried to raise the salinity, I dumped 2 kg into 500 liters, and it barely moved the needle.

It is very wrong to pour salt directly into a live aquarium. Dissolve it separately and add it instead of osmosis water. Slowly and smoothly. And a float is already an anachronism. A refractometer is much more accurate and not that expensive.

Yes, by the way, I wanted to ask how to properly change the water in the aquarium. I do it like this: I turn off the auto top-off, drain the water, and then use a hose to fill in the same amount of water that I drained... I understand that you suggest filling the replacement water into the top-off container and waiting for it to fill up... won't there be any salt deposits in the auto top-off in this case?

Christopher

That's not correct. I wasn't talking about replacing water, but about adjusting salinity in the aquarium by adding salt. I do the replacement like this: I prepare water with the desired salinity (1.025-1.026 SG) in advance. I drain the old water from the aquarium (siphoning detritus in the sump). I add fresh water (with the same salinity as in the aquarium). :-) I have a peristaltic pump. There’s nowhere for the salts to settle. I'm also sure that in your auto top-off, a pump is used that is suitable for seawater (most of them are).

Yes, it was at the dawn of my aquaristics back in June. How that lonely clown endured it all is still a mystery... I was pouring salt directly into the sump with a one-liter container. And one more question: I plan to do water changes of 30 liters on a 500-liter system (aquarium + sump) once a month. Did I make the right decision? Assuming all the inhabitants are feeling good right now and there aren't many corals...

Through auto top-off or a return pump from the sump - this is if you want to change the water parameters or gradually introduce some chemistry. When I do water changes, I pour fresh water directly into the aquarium, except through a 12mm hose - I place a bucket on a ladder, put the hose in the aquarium, and I can walk around for about 15 minutes.

In one of the recent issues of the Coral magazine (I'll check the issue and page at home if it's important), it is mentioned with some math whether water replacement is beneficial and how it affects the concentration of harmful substances - nitrate, phosphate... So the conclusion of the article is that it's almost useless. If there is no cause for concern, I wouldn't change the water. Many people do not replace the water. They add a small amount to compensate for the loss from the skimmer and during minor cleaning of the sump (where detritus usually accumulates). But we're talking about 30-40 liters per ton.

I believe that substitutions in such proportions are absolutely pointless. If you are going to do water changes, then about 20% per month. But each system is unique, and you need to find your own "ideal" option. I change 10% every 2 weeks. PS It is also recommended to aerate freshly prepared seawater for about 12 hours. PPS I also read a recommendation that initially you should aerate osmosis water for 10-12 hours before adding salt.

And what is the purpose of aeration? To raise the pH) So when replacing 5-20%, it's like a dead man’s band-aid.

Resource potential to raise.

Then it will be faster to ozonate.

Sydney

Maybe... But what is easier to do? Turn on the compressor or buy an ozone treatment system?
