Re: Good filtration for small planted tank?
I have a 10g with a Penguin Biowheel on it, and I keep the water level up so there is no splashing, and also I removed the Biowheel to reduce CO2 loss. A canister would be ideal, to reduce aeration of your filtered water, but an HOB is doable if that is what you have. I dose Excel on this tank, but I have also used the yeast CO2 method with a ladder diffuser, though this takes up a lot of room in such a tiny tank.
I have also kept a "natural" heavily planted tank with no filtration at all, except for the plants themselves. Keep your fish load somewhat light, provide decent lighting, and dose nutrients and you don't need a filter. The plants did great and it was nice not to have anything at all plugged in or hooked up to the tank.
