    i got a new 30 gallon aquairum for my zebra danios. Should i use an internal filter or hob filter with a sponge filter for bb to grow on so i can really clean the hob or internal filters good. What are your preferences for this internal or hob

    hob in my opinion

    Hob is way better if you want my opinion. You have a whole lot more options on getting the media you want, more area for bb, easier to clean and best part they aren't taking up valuable tank space.

    Canister, but hob if that's the only option.

    For a 30 gallon, a HOB is probably your best bet. An aquaclear jam packed with biorings or other ceramic media will be plenty unless you like to stock on the heavy side. Another great thing about ceramic media is that you almost never have to clean it. You'll probably want a sponge at least for mechanical filtration however.

    i can get a canister but i don't think that 15 zebra danio would need it

    Really ? why would they need an HOB or internal filter ? Canister filter is the way to go for more reasons than just filtering, they don't add noise & vibrations to aquarium. The more noise and vibrations you eliminate from the inside of aquarium the happier your fish will be.

    I run two hob's on all my tanks except my 40b high tech project (going to use a inline co2 reactor).

    Two small hob's would create adequate filtration, provide a huge space for media, provide a safety factor, and you can use one for your quarantine tank.

    canister is the way to go

    Why not both? I currently really like my AC 110 with a small underpowered sponge filter in the corner where the AC can't really reach.

    The pump is rated for 5x less the tank size lol, but it's only there for that hard to reach corner. Cost be like 6$ for filter and pump. Doubles as a crudr airstone.

    actually i might do that and use both....i got about 10 unused filters so i trying to use them

    na...i wouldn't need it for these fishes since they wouldn't have that much bio-load so the canister would be wasted...and then to i got both internal and hob filters that are not being used.

    No such thing as too much filtration.
