Wow, yeah that's a lot of RowaPhos!

So where the heck is all the PO4 coming from? Your tank is setup up in a fashion you'd think it would be nutrient-poor. What do you have for clean up crew?
The Aquaforest foods (Amino Mix, Build, Energy, and Vitality) are designed for use
after achieving ULNS so you can tweak exactly how you want nutrients in your tank. You're not supposed to use them in tanks with nutrients. Also "Energy" has copper in it which promotes the pastel look, so if you're looking for rich colors, don't use Energy.
Yeah that Big R Corals guy has a lot of nice stuff. Too bad he's in Texas (iirc).
