I'm running a 2 liter DIY CO2 system and I just recently moved. The previous setup was running fine with the tank on the bartop and the bottles about 8" lower on the counter-top. Now I have to put the bottles on the floor and I woke up yesterday to find my tank level a bit lower and my bottles full of aquarium water. Does anyone know why? I know that it could have created a siphon since it was lower but someone has to be running the same set-up. Any advice?
