Phosphate down from 1.03 to .29 in 1 week

Phosphate down from 1.03 to .29 in 1 week

I used 1 cup Ferris oxide in a reactor
Also used a micron filter and am now turning off return when feeding
I think the Ferris though is the biggest contributor
So now (after months ) of high level now I'm close to “range” do I discontinue Ferris? Or leave it? Thank you

If you took the reactor offline, you can observe whether the system is generating PO4 or it is stable.

Agree with above. Turn the reactor off and see whether the levels are stable or start to rise again. I would be careful. Large swings in phosphates quickly can make corals very unhappy if you have any
