Ok need GFO gurus to chime in...magic formula?

[Sagecritter4life]

Ok so I have a 20 gal fishles coral QT tank running with a fluval HOB type filter. My question is how much GFO should I put in bag in filter to lower PO4 to roughly .o5-.1 from current level of .25 ?? Gets up to .35ish right before biweekly water Change.

Zoas-Duncan-Yuma and snails livestock wise doing well and levels are giving me some unwanted algae..go figure lol.

Pondering phosphate Rx as another means

My other main parameters are

Amm 0
No3 - 5ppm (red sea)
1.025 (refractometer)
Alk 10 (Hanna lr)
Temp 78.2

I feed reef roids one time/week
Fauna marine lps pellets one time/week
And few pellets of marine S for nassarious snails every couple days.

Thanks for any knowledge [emoji106]

Never use GFO.

Just dose PhosphateRX as needed. Usually once a month.
