With the huge variety (from name brands to knock offs), which brand of canister filters have you tried and which ones would you recommend to others?
I have to say that I’ve used almost all of the brands (Eheim, Marineland, SunSun, even the cheap Top Fin brands) and they all worked well. Just make sure that you set it up correctly, and don’t stuff a lot of filter media since that tends to burn out the motor in the cheaper units. I also would HIGHLY recommend using some type of lube on the O-ring seal and even on the tubing to help stop leaks in the future.
