so i tried an one inch soil layer with 3 inch gravelin my 65g. i have outrageously high phosphates and brown hair algae everywhere. lights r 3 w/g and on for 7 hrs a day so i know that isnt it. i fert twice a week with a 30% water change. im thinking my soil (miracle grow) is leaking a lot of phosphates so i was gonna replace my substrate with either florite or fluval's stratum....suggestions? idk what is in fluvals stuff but i know flortie has a lot of good.

ps: i tried phosphate sponges...no effect on my high levels :/ i had the set up for a few months

Are you trying to figure out why the soil method didn't work for you, or are you just wanting to switch to a (more) inert substrate?

What specific kind of soil did you buy? Did you rinse it first? Miracle Grow generally comes preloaded with a starter amount of fertilizer.

That probably wasn't enough rinsing for the soil. I just put in a new substrate last month, and I soaked the soil and changed the water every other day for a couple of weeks. For the ultimate in how to prepare soil, see the "Mineralizing Soil How To" thread, or this step-by-step

If that's too daunting, you may be happier with a gravel-only substrate. A number of us are now enamored of Saf-T-Sorb. Delivered to your door for < $20 from http://www.drillspot.com/products/1476408/Moltan_7941_Montmorillonite_Clay_Absorbant_40_lb
It's a great cap for soil.
