• Nitrates in water

  • Antonio

How can I quickly reduce nitrates in water? Are there any treatments available?

Katherine

First, figure out where they come from. Eliminate the cause - the nitrates will disappear.

I think I'm feeding the fish too much and incorrectly, specifically frozen brine shrimp.

Derek7322

Switch to dry food. Reduce feeding. Make a water change.

What feed is better to use?

Brian6895

Why give up on freezing? Maybe it's better to focus on improving the filtration system?!?!?!

Christine

And it's important to choose the fish (and other inhabitants) according to the volume and capabilities of the filtration system. P.S. Then you will be thinking about how to raise nitrates instead of lowering them...

Advisors, this is not about freshwater, but about a marine aquarium. Nitrates are harmful in any amount there.

What you are saying... But we are talking about a marine aquarium, and I thought we were discussing a terrarium... Alright, now seriously. Nitrates and their origins, as you say, should be present in a marine aquarium, but at a low level. This is not just my belief; practice shows this, and I have very little experience as an advisor. Best regards!

I switched to dry food 4 days ago, feeding once a day. For 100 liters, I did a water change of 15 liters, but the nitrates did not decrease. Can I do a 30-liter change? Will it cause an imbalance? I measured with a salifert test. How else can I reduce nitrates? Where are they coming from? Can I do daily changes of 10 liters? Or could that be harmful? Can I add a carbon filter element? What is the most effective solution among all of this?

The main thing is to properly balance the system according to the parameter: Livestock - filtration system! If this balance is not achieved, all methods are useless. Fighting nitrates: 1. Water change 2. Algae scrubber in the sump (the bigger, the better) 3. Vodka method 4. Biopellets (reactor) 5. Nitrate reactor 6. Use good live rock in the aquarium 7. Reduce the amount of livestock

The Boya 550 aquarium doesn't have any of that and there's no place to put it, the scrubber, and all the reactors. I use quite good live rocks.

Brenda

I just listed the methods for dealing with nitrates for you..... P.S. I know of one Resun 92L that has been modified (drilled) for use with a 100L sump, and there are no problems or excess nitrates there! Moreover, the sump is so well hidden that you would never guess it’s there! The aquarium is packed to the brim, but the filtration system is top-notch! In your case, get rid of the excess fish.

The sponge gives nitrates. Nitrate factory.

Joseph2576

I threw away the sponge today and all the bio balls, now the first compartment is empty, can I put some kind of filtering material there?

Scott8536

A pouch with antifos.

Michael3221

There are 2 pieces of phosphate at 0 or 0.5; my main goal now is to reduce the nitrates.

Nicole7268

Coral crumbs. Fraction 1-3 cm. And softies, they love nitrates. Softies are not in the compartment, but in the aquarium.

I support it, especially regarding point 1.2.7 (you have point 6). Reduce the load if you don't want to deal with filtration. Some use macrophytes directly in the display, but this method is not entirely good due to a number of reasons (from the need for constant light to the tricks of various heteromorphs). There are also forum members who change the water 2-3 times a week (!!), by 10-20%. (That's tough too.)

Clear the rear compartment of sponge, ceramics, and especially bio-balls. If it's really necessary, you can create an algae scrubber in the middle compartment. The back part of your glass is covered with black film. Cut it where the middle compartment is and place the lamp behind the aquarium. Alternatively, you can buy a lamp that can work underwater. Such lamps are sold in pet stores. Place live rock in the rear compartment. The vodka method with your protein skimmer will lead to unfortunate consequences.

Sarah

Did you buy the tubastrea for this aquarium?

Not enough brains to stop, it will go out there.
