Messaged you back Rogger.
Air valve is not letting me control the water level, the gatevalve, I change it from high to low, but it either adds more bubbles when I go high or takes them away if I go to low. Been messing with it for too long and its just getting me aggrevated. I have a MRC CR-2 dual chamber calcium reactor and that keeps leaking from the bulkhead at the top, this companies products are really starting to **** me off.... I hear so many good things about them and I don't know if its me or what. I have the MRC nilsen reactor and it works great, just wish these other two important pieces of equipment would start working... going to bed, will get back to it tomorrow...
