I ahve been using a home-made HP CO2 system for several months now. Unfortunately, it has become quirky, and not behaving properly. I have a solenoid controlled by the light timer, and a "needle valve" from home depot, and a check valve to allow bubbles into the tank.
For the past month or so, the gas was impeded by something. I opened and lubed the needle valve, bought a new check valve, and still, it seems that the bubbles work fine once they are going, but if the unit has been of for a while, it can't seem to get started again w/o me opening and then turning down the n-valve. I tried turning the secondary pressure up, and down on the gas regulator, but still the same issue: the gas does not get going again unless the valve is opened and then turned down.
I have a poll question for all of you using : how many use CO2
b- yeast method
c- HP bottle
--- and is it...
1- always on
2- timer on/off
3- pH meter on/off
I am going to try #1 for a while
