I'm looking to get a new canister filter for my 75 gallon tank. I found good prices on the Rena XP3 and XP4. To save money, I'd like to buy the bigger one in case I ever get a bigger tank.
Do you think that the XP4 would be overkill? I had a feeling that the XP4 would put out too much water and make currents in the tank that the turtle might not like.
