Have you ever measured the Phosphate in your effluent using the ARM?
No, just the tanks and they are 0.00. i will though just to check. i dont think i get many if any, my macro algea never does good in this tank and all corals and coralline grow well.

did you evacuate the reactor compleatly of air before you pluged in the pump? open up the effluend drip line fully open and then while the reactor is running pick it up and gently bump it back down to dislodge all air trapped in the media.
also when you say you turned off your CO2, how long did you wait? it takes several min's before you stop getting bubbles of CO2 after cutting it off.
