The controversy between the Canister Filter and the HOB filters. As most of us know there's a big following of both filter types. For years with smaller tanks the HOB was the filter of choice other then the sponge filter. Now we also have the smaller canisters available for small tanks. For the HOB's the recommended filtration rates are double that of the canister filter due to limited capacity of the filtration media. Something else that you here from the HOB side is lower initial cost acquisition of the units. The aquaclears are about the best on the market for HOB, I'll go with the 110 model. A quick look on Amazon and both Ebay the unit averages between $79-89 starting prices. On the the canister a decent middle of the road canister filter that can handle a tank the size of the Aquaclear 110 is the Marineland Magnaflow 360's. Made for supporting a 100 gallon tank and at a good price point for buying if you do a little searching. Over the last 2 months I have acquired 2 more of these filters brand new off of eBay for a total cost of $153. I know the complaints on canisters is they are expensive, heavy, and take to much time to clean. Here's the deal they can be heavy my Fluval FX 4's are heavy when they are full, it's a big filter. But when running a pair of filters on a tank maintenance is cut down on the filters. Start to finish you can really clean or add media in about 20 minutes, plus with the added media capacity inside the canisters you can have extra cycled media available for a quarantine tank or to give to a friend just getting into the hobby. So for those that want to get into a canister filter and don't really want to go with completely cheap, there are alternatives out there. It's a matter of a little digging.
