| Re: Korallin Calcium Reactor and PH Controller i had the same problem as scott. what fixed it for me was setting the drip to almost a stream and then adjusted the CO2 to bring the eff to a ph of about 6.5. then watch the Ca/Alk in the tank and adjust the the reactor from there. with the almost stream i have had no CO2 build up in the reactor. when my tank was lower on Ca/Alk the reactor was a PIA and always got that CO2 build up. but after adding many corals increasing the demand, the reactor has work great. i think the korallin is better suited for higher demanding tanks, JME. |
