I have my biopelelts reactor up and running, and almost nuked my tank. I picked up the SMR1 reactor and had the flow too high (even though it looked like a gentle tumble). I also did not have enough of the discharge from the reactor getting skimmed. The tank had a white cloudy appearance, which is an indication that cultures were not contained to the reactor.

As a result, PH dropped to 7.1 in one night and all my coral are in shock. Today I cut the flow to the reactor by about 50%, and all pellets still tumble. I also hooked up an airline to one of my powerheads so I am flooding my display with air.

SO, for anyone considering this for their tanks, I would recommmend plumbing the reactor discharge directly to the skimmer. Those setups seem to be the most stable and efficient.
