yeah and if you like that controller look it up on ebay and get it with a ph controller for under 160.. such a good deal use the co2 controller for your tank and a timer keep the ph controller and use it with a small pump to keep your ph in check..
hazeywonder Reviewed by hazeywonder on . how do you regulate the CO2? Would i be able to spray seltzer water on the plants (carbonated water...with CO2) to deliver CO2? does anybody do this? i can't think of any other way to deliver a good amount of CO2. Rating: 5
