Mitch,
I've never tried the agrocreat but Kim has made a whole bunch of this stuff last summer I believe.

thanks everyone for the help...the tank has been up for ~2 years but really only had this much lr for a year, and i have only been running it as a reef for ~6 months....i use tech part A and B for calcium. I wanted to set up a reactor but its too much $$ right now, plus i dont have a sump or anything and its in my bedroom so i need the least clutter possible. I have kinda decide it add a bit more rock on this advice to build up the right side to the very top and maybe to ad a few peices on the right side. How much do you guys figure i will need to do this? thanks again.
