Hi Ole Bob, What happens when you increase the anode to cathode spacing?
Andy From: Robert Berger I do not recommend air bubblers as I do not know how much CO2 is being added to the CS. Also I think that the agitation is to weak for anything larger then about a quart tank. I bought the pump at an aquarium store. It is rate 35 to 70 gal/hr with a head of 18". Since I am not elevating the DW it should be running near maximum output. The 2 gallon aquarium is 12" long, the anode is at one end and the pump at the other end directed towards the cathode- anode. Its like this PUMP---CATHODE--ANODE. Anode to cahtode spacing is 1.8"
