    Hi,
    I am thinking about buying a canister filter to use on my new tank. I have a DIY trickle filter that came with the setup, but I hear that those filters will off gas the CO2 (is that true? would a lid help?). Anyway, I came across a cheaply priced canister. It looks like an Ehiem but Catalina makes/sells it. Has anyone heard of Catalina CA 918 CANISTER FILTER? It sells for $50

    If I use this filter, it will be used on a 75 gallon tank with an over flow. Speaking of which, will overflows off gas CO2? I guess if it does, I could raise the drain pipe up higher. Any suggestions? Any experience with the above filter? filter advice in general?

    Tom has some decent threads on wet/dry filters and offgassing. Essentially, seal up the BioTower on the wet/dry. Airtight if possible to trap all CO2. You can also seal up the sump as well. I didn't bother doing this with the BioCube I have but there's not much the CO2 can do other than spill over the dividers and hang out in the "sump".

    Thanks. It looks like I would need two of the cheapo's for a 75 gallon tank, so I think I will experiment with sealing up the sump first.
