Hello Use...
If you're an aggressive water changer, if you change out most of the tank water weekly, you don't need to spend a lot on a filter system. They just take in polluted tank water and return the water to the tank a bit less polluted. Canister filters are pricey and take a lot of time to clean. They don't work any better than a simple dual sponge filter that's 10 times cheaper. Both aerate the tank water and that's pretty much it.
Here's a good tip: If your tank is small, up to 30 gallons, change out most of the water a couple of times a week. If you have a larger tank, change out most of the water weekly. Do this, and you'll have few, if any tank problems.
