CO2 output straight into a filter?
I have both a pressurised and DIY CO2 stytem running in my Fluval Edge 23l. When i moved to the pressurised system, instead of give up on the DIY which works well I though that it would be a good idea to output the DIY system via a sintered glass atomiser stone into the bottom of the hang on filter, under the sponge mechanical filter. My thinking being that the CO2 bobbles will get caught in the filter sponge and therefore have a longer time submerged and therefore diffuse more efficiently.
My question is whether this will affect the biological filtration at all. What effect if any will the addition of CO2 bubbling have on the bacteria, and will this be detrimental?
I have a drop checker and regularly check Ph and ranges are good even with both pressured and DIY systems running
