Hi folks. I am looking for a wet/dry filter for my 60gallon. A couple of clear acrylic units I've seen on ebay (about 20"x7"x17") are perfect size for under my stand, but they appear to be topless. My concern is that in the biochamber, the trickling will vent off CO2.
Are there any retail units that have the biochamber sealed? Does such a thing exist when the biomedia should be well oxygenated?
