I have a DIY co2 system with a DIY powerhead/tube reactor. Is it possible that my HOB filter could be causing my co2 level to drop? I was thinking that maybe the water circulating through the filter and splashing back into the tank was causing the co2 to gas off.

Hi,

yes this could in fact lead to c02 loss. Anything you can do to reduce the distance of the fall will help. Keep the tank level up to as evaporation will increase the fall.

If nothing can be done, you may want to try raising your bubble rate to compensate. Tank size, etc?
