Useful for binding ammonia/nitrites
This stuff is great for binding ammonia and nitrites. I started using it after a bacteria crash and I now use it as my regular water conditioner for almost all my tanks. In my experience, it did not actually remove any nitrites or nitrates, but it certainly keeps the fish more comfortable in a crisis. I also only use a slight amount more than the regular dosage to detoxify (necessary because our water is highly chlorinated here) and do not use the higher dose as instructed on the second part of the directions label because when I did, my fish appeared very stressed out and lost some color (though I should note that I did not lose any fish, a water change and a lower dose did the job just fine after). I'm still giving this a 5 star review however, as it was a life saver for a tank crash and seems to be comparable to the higher priced products that are meant to bind toxins and keep your fish safe. I don't think there are any products that can truly remove the nitrites and nitrates, and no matter what if your levels aren't going down you can't avoid the extra water changes. But we keep this stuff on hand at all times now.
