Pufferpunk;1168345; said:I use canister filters for biological filtration on tanks over 40g. Otherwise, I use HOB filters. My canisters are only cleaned out every 4 months or so but if you're using it for mechanical filtration I suggest rinsing the material in there often, especially with something as dirty as a turtle. You'll still need to do huge water changes very often too.
When I kept them, I used a river tank set up. See the last 2 tanks in my sig for a pic.
