Low tech filtration upgrade?
I'm doing a low tech 10g and I have an AC20 for filtration. It's on the fritz and I'm looking to replace. I was told a HOB isn't good for low tech anyways because of the gas exchange it causes. Apparently since I'm not dosing CO2 I wanna keep all the carbon I can?? Makes enough sense...now with that said I've looked into a few filters and what does anybody think about the rapids mini canister? It does 80GPH and seems to be the best bang for the buck. Also saw the tetra whisper internal filters...more powerful but I'm limited in space as is. What do you guys with smaller low tech tanks use?
