Just as a heads up to nitrate dosing from my experience. I had a 30g frag tank that was wall to wall and up them frags. It read hard zeros for a while with corals paling out. I bought the ESV nitrates and dosed 1ppm/day per their instructions. It took almost 2 months to get a nitrate reading by the following day. Depending on how long you have been nitrate deficient, the corals will suck it up pretty much immediately. Granted, this tank had far more coral mass/gallon than most, but be aware.
