po4 in my LR HELP

[donkey77]

Got my LR from a lady that i dont think took care of very well, been having algae issues ever since and i got my Live sand from her too. So i thought it was my sand and i removed most of it almost got it all, still having issues, i run carbon, and Foz down, still looks ****ty, so is it my LR and what can i do about it, take it out and boil it, vinegar bath, pressure wash it and let it sit in the sun for a week i dont know. the pix are not the best but you get the idea

how long have you been running Foz down ? It may not take out all of you PO4 immediately. Generally these sorts of things take time. How much time depends on how much PO4 is trapped in your rocks. TAke it out to preassure will only clean what's on the surface but won't resolve the issue of what's trapped inside the rocks, ie, P04. Continue your use of Foz down and give it some time to settle out.
