Endgin33, itís funny that you should ask about the pump. The pump started to act up last week. I guess ignoring the issue didnít resolve it.
I heard some weird noises, even through my ďquiet boxĒ, and found that the pump was cycling on and off every several minutes. I disconnected it and tested it in difference conditions, even submerged in cold water, and it continued to cycle on and off. So, lesson learned Ė donít make a mag drive work for its supply water. For now Iíve closed that portion of my loop and put a powerhead in the tank with my CO2 feeding into the intake of the powerhead. Iíve also added a heater to the tank since the heater was on that loop as well. That works for now; until I get around to redesigning the heater/reactor and ordering a new pump.
Bunny 1978, are you sure you are getting 100% dissolution, or is it possible that some of the gas makes it through your media before itís 100% dissolved? In any case I donít think that bio balls would solve the problem. The way things are set up now the bubble doesnít have to grow that large for the water level to get below the pump inlet. And there will always be a small bubble that builds in this type of reactor. I think that moving the pump down will be the best solution for me. I have even considered putting the heater on the right (or inlet side) and the reactor on the left (or output).
