How to raise Phosphates

[WVReefJunkie]

I am dosing Nopox to lower high nitrates. I was running gfo for phosphates beforehand, but my phosphates are now zero. They have been at zero for over a week, nitrates are now at 16ppm. Should I raise Phosphates, and how do I do this? Thanks.

Did you take your GFO offline yet?

 

[WVReefJunkie]

Yes

I have noticed my coralline on the overflows are turning white some.

If you've taken your reactor offline you can dose the Seachem Phosphate additive (sold on Amazon) or you can increase your feedings of pellet/flake foods. If you are rinsing frozen foods before feeding you can skip that, too, to help bring them up. It will take some time to do that, though, as you may have a buildup of organics that once phosphates enter the system they will be used quickly

I do have some cyano on the sand bed.

I didn't think I would be able to raise them since Iam still dosing NoPox

What test are you using to measure PO4? Are you sure it is zero?

Yes, Hanna Checker low range.
