I have 4 - 20 gallons with Eheim 2232 filters. 2- 5 gallons with Aquaclear HOB filters.I'm curious to know what people are using in smaller tanks that are 29 Gal. or less for filtration?
- Combination of filters? if so, which combination?
- Hamburg Mattenfilter
- Small Canister
- Refugium - some people use them in different configurations and for "several small tanks"
- Other - is so what?
