So I just started up my new frag tank a couple/few weeks ago and unfortunately it was a rush job that required me to not allow my tank to cycle and take a chance that it wouldnt have one. I used alot of good LR and everything seems to be going well. The only problem was, my nitrates were a little high. Around 40ppm. Ive never really been one to worry about chemistry as I do enough water changes and I feel as though I can tell by looking at the coral if anything is off. Anyways, I came across this product called Nitra-Guard bio cubes. I thought I'd give it a shot and I have to say I am impressed. My nitrates went from 40ppm down to 5-10ppm in about 4 days. I had been recommended using vinegar/vodka dosing but wanted another solution as the tank is brand new and my luck i'd nuke my tank. Anyone else tried this product? What do you do to lower nitrates?
