New Co2 Method

[julioarca]

I am retrying my Co2 system after having many failures due to overloading my fish tank..Discus were not too happy.

I have a Red Sea dIY Co2 system and have it connected to a double valve outlet. One pipe goes to my venturi on the filter outlet, the other goes to a 750ml plastic bottle which I have fitted a pipe connector to. I know the bottle is water tight and I also know that when it reaches a certain pressure it hisses a little to release it. I also have a bubble counter on the side too.

Soo I have adjusted the outlet to show approx 1 bubble per sec going into the tank andhave the valve fully open going into the extra bottle so it is acting as an over spill but I know it will seep the Co2 once it gets too much in it. Might this work?

Lets see

So your problem is your DIY mixture is expanding too much and you need an overflow? If I got that right then just adjust the yeast mixture so it doesnt swell as much
