Phosphate reduction

[Mark Bradley]

I have a reactor that I use rowaphos with. It seems that even if I follow the rowaphos site, for suggested amounts, it soon needs replacing I.e. within 48 hours. My phosphate seems to want to hang around 0.3 and to change this down I’d have to refresh the reactor almost daily - does this seem right? If I do change things daily hopefully I will get it down below 0.1 (closer to 0.03) - once there will it be easy to maintain there or am I always going to be in the ‘change daily’ routine. I don’t heavily feed the fish and I use reef roids twice a week with the corals. Any thoughts would be appreciated.

can be...you could need a couple of kg to get it down to .03, check on one of the Rowa calculators.
Rowa can exhaust easily within a day if the PO4 is high.

What size tank?

What test kit are you using to test the phosphates?
