Hi guys wondered if anyone here uses one of these?,i bought one 2 days ago and i,m having problems getting the unit to knock off the co2 supply,the unit has a built in solinoid,the instruction for the auto ph setting asks you to check the kh in the tank input this into the computer and the computer sets the optimum ph for your kh,i've done this the kh in the tank is 7 and the optimum ph value calculated is 6.97,but the unit wont allow the ph to go below 7,it also allows you to alter the switching points at which the co2 is supposed to be switched off i.e 0.05 under the optimum ph but this isnt working either cause the ph wont drop below 7, any ideas on what could be wrong? the ph probe was new and the one for the system. thanks in advance Dean.
