High phosphates-using reactor and can't get them down

[maron6977]

If you want to get your PO4 down , use Fozdown . Contact TimT on forum. Mine were as high as 70 at one time . The stuff works instantly & way cheaper than GFO . Can't tell you how much I spent on that stuff .

Now my PO4 is down to .00 & quit using Fozdown a few weeks ago .

Now trying to raise back up !
