| | Re: bio-wheel or power filter
I have 2 HOB filters on a 25, one of them is a bio-wheel. I am changing to cannister, not because they don't work, but because the cartridges don't seem to last that long. The cartridges also come with charcoal, so even if you don't want it, you have to use it. The exception that I know of if you should go with an HOB filter is the AquaClear. It is an extremely quiet filter and it has ceramic? media in it that you just rinse out; no need to buy expensive refills. Water turbulence is bad for co2 dissipation, therefore I don't think the bio-wheel is a good choice.
