I wanted to get a HOB
filter for a 10 gal
. I already have a penguin 170 for my other tank. I like it fine, except the monthly cost of replacing the filter. I was wondering if anyone knew of a HOB
power filter that was as economical as a canister filter, where you just rinse a sponge and refill a reusable bag. I have been researching and I have the impression that the aquaclear 100 and the whisper fit this expectation. Am I correct? Does anyone have any experience in this regard? I don't want to buy more filters.
