  1. Default Under Gravel Filter ?

    0 Not allowed!
    I just set up a 20 gallon long freshwater aquarium on my pass through. I wanted it to be seen from the kitchen and dining room without a filter hanging off the back. So I put in a under gravel filter in and it looks nice but I don’t know if that will be the healthiest thing to do now after reading so many posts here. Any input or ideas are most welcome…

    It is ok I guess but very limiting. For one thing, eventually you'll have to get in there and clean that sucker out. You are going to have a ton of build up under the gravel. You are also limited in what plants (if any) you can put in there. Nothing that roots. So floating plants and stuff like anubais and java fern that grow on the sides of rocks and driftwood. But even they will send roots down if not high enough off the substrate. I don't know the layout of your house or the place in which you put it but have you thought about hanging a filter on the side instead of the back or front? What about a canister filter with both intake and outtake on the side.

    All I've ever read is negative things about the under gravel filters, but I understand why you used one. I've never had or used one.

    A canister filter would just have 2 hoses running up to it...would that be too distracting for what you want to accomplish?

    like slaphappy suggested..more expensive, but a canister filter housed underneath the tank in a cabinet would work as well.

    Thank you all so much. I have been reading on Canister filters this morning. I have a glass hood and it only has a plastic strip along the back side to cut for any openings for my filter. I wish I could hang a filter off the short side but I can’t cut through the glass. I am rethinking many things now. I was hoping so much that an under gravel filter would do it….I have much to learn!

    0 Not allowed! I am going to get a Canister filter. Should I just take out the under gravel filter? Do you think it is over kill having both? I had also never though about having to clean underneath it...ugh

    I'd take it out. Cause like you said just the thought of cleaning it out makes you tired. Especially after you get all your stuff in the tank and all your fish. Fun times. Is this your first tank?

    I had a tank about 30 years ago, so this feels like my first tank. So much has changed. It’s one big learning experience-LOL

    Well just to cover all the bases, are you familiar with the fishless cycle? Defiantly the way to go and there are stickies in the beginner section concerning it.

    On an unrelated note, if I read correctly this is going to be quite an open tank. Make sure you choose bolder fish that don't mind being a bit exposed.
    Good choice on the canister filters. Aquarium technology has improved. Over the years.
