Well my tank has almost always run really low nutrients. The last test was .01 po4 and 0 no3. I am joining a grow out contest and wanted to get a little help with some Reef Roids. I started feeding it last weekend and today I checked my nutrients. po4 is .18 and no3 2.5, granted I heavy handed it. Not bad numbers but not what I am use to seeing come up on the test. I think I am done with Reef Roids for now, lol.
I notice no difference in coral color and alk hasn't went up or down, so it seems the tank is just going with it.
