Also, what type of LED's are you using? I had one of those boards that are about a foot square with 225 LED's and it was worse than useless... I now use 6400k CFL's and all is good.
im not sure of the brand, ill check later, but i dont think the guy switched anything up from when he bought it.

ive been putting 7tbsp in my res every day (15 gal res) plus 2 air stones!

the leds are from Go Green Grow Lights the diodes arent the 5mm diodes and there is 2 blue wavelengths and 3 red covering the blue red spectrum
