    This might be a no brainer for some, but I have been using hang on back filters for some time. Now I am noticing through several posts that many are using sponge filters. So which is better? what are the pros and cons? Should I switch? Use both?

    For me I think the HOB does a better job mechanically filtering the tank and the sponge filter does a better biologically filtering the tank. I find that if you use sponge filters you have to syphon the fish waste more often then when using a hang on back because the sponge filter doesn't suck up the waste rather then drawing the waste near the sponge . Here are the cons and pro I thought of.

    CONS for HOB
    Uses more energy
    Not convenient when having multiple tanks
    Can be a little pricey
    Some fishes can get stuck on the intake

    PROS for HOB
    Uses less space inside the tank
    Mechanically filters the water better
    Easier to clean

    CONS for SPONGE FILTER
    Uses more tank space
    Doesn't look pretty
    Doesn't suck up waste as good as HOB
    Harder to clean

    PROS for SPONGE FILTER
    Biologically filters the tank better
    More convenient when having multiple tanks
    Uses less energy
    Recommended with fry and other breeds that get damage easily( bubble eyes)
    Those are the pros and cons I thought of. I'm sure there more. Both filter have there own ways and it depends on your situation. If you multiple tanks and want to go with a cheaper route then I would go with sponge filters. If you just have a couple tanks here and there a HOB would also work. But yes I would recommend using both so you have the best of both worlds.

    If you can, I would use both just in case one system breaks down

    I found that the best results come from using both. A HOB filter gets rid of larger bits of waste while the sponge filter traps smaller particles and buffers the water nicely.

    I don't like the sponge filters. They quickly lose flow as the clog themselves. Then there's the aspect of the fish waste just sitting in the water with the fish. Avoid......
