I'm about to order the Filstar XP3 for a tank that i'm planning on buying (it's going to be between 55 and 80 gallons). It just occurred to me when I saw someone elses tank, that these canister filters operate through a cutout in a glass tank.
I'm guessing the cutout is absolutely mandatory, huh? I actually haven't seen many tanks that have the cutout.
My turtles are getting big they really need more room, but I need to stop putting off the purchase of a new tank! Can I just ask at a petstore for tanks with the cut-outs for filters?
Thanks.
