  1. Question Headache....part one

    0 Not allowed!
    Why is it, the more I read, the more lost I get? I wrote about getting a 90 gallon aquarium. It came with an AC 110 and an AC 70. I was told two AC 110's would do the job. I decided to go with a black gravel substrate and have been told, by several people that have gravel, that I must get an UG filter.
    I read a very good post on here explaining the different types of filtration, and it was mentioned that UG filters don't do much except keep the water clear.

    What do I do ? An AC 110 + AC 70 + UG filter, or, just go with 2 AC 110's?

    Another part to this question....I plan on having some rocks in the tank, and was told to get egg grate to protect the bottom glass. I did. If I go with the UG filter, do I need the egg grate? Does it go under the filter or on top of it?

    IMO go with the 2 110's or a 110 and a canister filter of some sort. That way if 1 filter goes down you will still have enough filtration for the tank. It also is good to alternate the filter maintenance. Stay away from the under gravel filters, more of a head ache then they are worth. Egg crate is a good idea if the rocks are fairly large or you intend to go with african cichlids as they ten to re aquascape as they want lol.

    Well.....looks like you have two people with the same opinion finally! LOL

    Forget the UGF. If you have a lot of rock, it's a good idea to have egg crate to protect the glass but many don't. Perhaps for peace of mind? I also agree with the 2-110's but even for now, the 70 would work.

    A 90 gal would do better with a canister. Never heard of using a UGF because you have gravel. With the 110, and a canister the tank would be better filtered since canisters can hold a lot of bio-media compared to any HOB. Still, issue of cost does matter and canisters tend to cost more.
    Knowledge is fun(damental)

    A 75 gal with eight Discus, fake plants, and a lot of wood also with sand substrate. Clean up crew is down to just two Sterba's Corys. Filters: continuous new water flow; canister w/UV, in-tank algae scrubber!! Finally, junked the nitrate removal unit from hell.

    If I go with a canister, any certain size or brand stand above the others? I'll probably get thrown out for this, but I saw a canister filter being sold on EBAY, for a 200 gallon tank, and have been considering.

    They are expensive, but I'm a big fan of Eheim; well worth the investment. I have a few filters of theirs, a Classic and the Pro 3. Very durable, very quiet, and very powerful (with control over the flow rate).

    Thanks ! Eheim Pro 3 is one I looked at a little while back. I'll check it out again.

    Remember to buy more filtration than it is rated for. I'm using the Pro 3 on a 30 gallon. Massively over-filtered.

    If I had a 100 gallon I'd probably put one cannister at each end.
