I have a tank that has been giving me trouble with nitrates lately, and I’ve haven’t been able to determine the source of the problem yet. I went to the LFS yesterday to buy a nitrate reducing agent to help improve the water quality as a quick solution while I continue to do water changes, clean power heads, etc. Anyways, I was looking for Purigen because I’ve heard that it works well, but the guy at the store really insisted that NitrateLock was much much better and would fix all of my problems. It is a bit pricey, costing $30 for 500mL which claims to treat 50 gallons. I purchased 1L worth of it and put it in a reactor in my sump and let it go to town. I searched the internet for this stuff and didn’t find many hits, and cant find any testimonials from users. I just wanted to see if anyone at WWM has used it? Does it work as well as promised or did I just throw money down the hole?
