Help phostphates !
so i tried an one inch soil layer with 3 inch gravel in 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
