Not to be a technical weenie, but a whisper 2 is rated from something like 10 to
40 gallon tanks. The compact model is rated for up to 20 gallon tanks. Do the
fish or plants seem to mind? I would try the system without the biowheel. Watch
the nitrate/ammonia levels carefully until the tank has had a chance to re-settle
with the changes.
Well, with that many fish producing CO2, extra CO2 fertilization probably won't
help all that much.
But these are just my two cents.
