Haha that's quite true, however I always just assumed for florescent tubes the wpg rule could be used as a guideline, while for other methods like MH, SV, PC and LED it was obviously not functional. It's good to know its not really good for anything but the larger diameter Florescent's.

I contacted the city water lab today apparently they don't test P but got me a 2012 record of a test done by environment Canada reading 0.01 mg/L This means little to me though as obviously once a year test in a river is not a reliable number to go by.

I've been looking at silicates and algae growth and I remembered something about silicates in the water quality report I read earlier. Turns out Sodium Silicate is dosed and reads anywhere from 2.3-20.2 mg/L could this be my problem ?
