Cobalt aquatic total nitrate

adamsfour · May 28, 2026

I am fighting high nitrates in my tank. I have tried a number of products without success. One recent product I tried is called total nitrate by Cobalt Aquatics. Doesn’t seem to do anything and I am wondering if it’s how I am using it. Anyone use the product successful .

Doenst work or has very very limited results in a salt water tank . This is due to chloride ion competing with the nitrate absorbing ones . Incoming " do water changes" LOL

Try carbon dosing, Algae turf scrubber, cheato refugium or sulfur reactor. Dont band-aid it (water changes) fix it with more export.

There’s no media that will bind much nitrate from seawater.

Have you had much luck yet with any particular product or process, since you posted this? Curious since I am having the same issue and constant water changes is getting a bit much for me

I finally broke down and started running a sulfur reactor. All the other products did nothing. I started the Sulfur reactor on 9 June and Nitrates running in the high 30 and low 40. I now have a constant nitrate between 9 and 10. It takes many weeks to get the reactor up and running successfully and it’s still not 100 percent but it fell I am 85 percent there. It’s definitely not a cheap solution but once it up there virtually zero maintenance except adjusting the drip rate to fine tune.

Awesome thanks for that update! And ok, I may look into that myself too then.

Best of luck. There are a few good videos on setting up. The key is patience as it took me over 3 weeks until I saw any results and you have to start with about 1 drip per sec coming from reactor
