I have had my calcium reactor setup for about two weeks. I am having issues keeping the CO2 flow regular. It will put out three or four bubbles then stop for 10 seconds then do three bubbles again. No matter what pressure I have my needle valve on I cannot get it to be regular. I currently have the pressure turned all the way up to 50 PSI to get three bubble every ten seconds or so. If I turn it down below 30 PSI then the bubbles will eventually stop all together. Does anyone know how to tell if a regulator/needle valve has gone bad? Or does anyone have any suggestions on how to remedy this? Thanks in advance.
Also, with the PSI turned to 50 PSI my KH has gone all the way up to 14 and my CA is at 460. All of my corals seem very happy. As I am still very new to the whole calcium reactor I don't know if this is way too high. I have heard of people running their KH at 11 or 12, but never 14. Is this way too high? Also, I am not sure what my MG is because I don't trust my current test, and haven't made it to the LFS to pick up a new one.
