CO2 gassing and absorption

[gustavo85]

Hi, I have a 20Gal H tank with a DIY CO2 with an airstone for small bubbles and an Aquaclear 200 powerfilter. Now, they told me that the filter could be gassing off my CO2 because of the water movement and agitation. To what extent is this possible? And if it is critical what can I do as for filtration? If I should change the filter, then which filter?:confused::help:

Just have water level always high so theres not that much splashing going on. AC filters are great and unless you plan to dish out $80-100 more for a canister i would just stick with the AC..

I agree with BK, but in my opipion, I think the air stone is doing you more damage then you filter is...

I think he mean he's using an "airstone" as the diffuser, not pumping air.
