Posted	Calcium reactor & CO2
06-05-2006 09:23 by Mathew Hutchinson	I fitted a calcium reactor and CO2 tank to my tank a couple of weeks ago. I have set my PH monitor so the CO2 only feeds into the calcium reactor when the PH in my tank is above 7.80. Everything is working. The effluent from the calcium reactor has a PH of 6.25, the tank hovers around 8.0 and the calcium test now shows 800!. I have the CO2 feeding in 24/7 if the PH goes above 7.80. Some books say set the PH monitor and soloniod valve on a timer at night. Is anyone an expert on this? do I sound to be on the right track? thanks

Not sure of the long term effects of keeping the calcium this high but I expect it will start to precipitate on everything equally the alkalinity may be a touch high as well. Generally people set calcium reactors to dose according to consumption rates of the tank I think you have yours set a little high I would try just running it at night.
