Yes I did tape over the holes. To me "recirculating" implies a closed system. Works great for me. I am getting 6-8 weeks out the media and picked up +- .25 on pH. I have not measured household CO2 to know what kind of concentration I am working against.
Skimmate production remains unaffected.
@Rostato is there some risk in doing so that I am overlooking?
That was my thought as well. It seems with (at least the reef octopus) all the holes in the top it would be sucking in a lot of fresh air, probably way more than recirculated air. My only concern would be buildup of methane gas or something.
I'm getting 1 week of life out of my co2 media with a "recirculating" design which doesn't seem to be the average from other posters.
