The best thing u can do, is do a poor tape job..
Sounds stupid, but pressure has to release somehow and the siphon is constanly pulling air down.
I tried cutting small holes and found it wasted co2 for some reason. The middle divider has a small section where the corners meet and there is a small gap leave that kinda open by stretching the tap across and pressing down evenly, but with ur whole hand, dont try to fit the tape down in the grooves. This will be ur pressure release. U still want it to hold some pressure. Just not all
In the end, ur tape will lose the constant battle and pressure will find the weekest spot.. ull soon learn where that is and adjust appropriately.
If u seal things too well air will build up in the wet dry section and go under the baffle, u have huge bubble explosions about every 10 seconds.
All that said. After u find the right amount of pressure to hold. Adjusting the siphon tube will control a lot of the water level in the tank and overflow box.
I aim for a 1 inch difference in water level from the wet/dry section to the sump section
