I'm using red sea pro test kit. I got a 12.00 reading for nitrate in high range and a reading of 0.02 or 0.04 for phosphate, its hard for me to tell the color differanse. I just started with a few frags of sps in Feb . a slimmer, setosa, purple and pink stylo and orange didgi. All have good PE and the slimmer is incrusting, but my pink stylo is looking a little brown. All my favias and chalice are growing great.So how terrible is that 12.00 nitrate reading for my SPS?

It all about the mark up too. Acrylic can be pricey, I built a sump at the beginning of the month and for a sheet of 4 x 8 x 1/4 acrylic was $140.00 wholesale. I went in to a company that manufactures parts for boats out of acrylic to see if I could by there left over/scrap and they company wanted to charge me $375.00 for scrap.
