HOB or canister??

I've got a 55 African cichlid tank that I'm running two HOB's on but I'm wondering if a canister or two would be the better way to go. Any advice? Also has anyone had any luck having a planted tank with Africans? I've done some research and it seems like going with two smaller canisters is better than one bigger one.

Anubias could work with Africans. They are tough and come in a wide range of sizes. This is just my opinion; however, HOBs are so much easier to maintain and I think they are appropriate for a 55.

Well I see you're running two Marineland Penguin filters and I'm not a big fan of cartridge type HOB filters (but I do like the Hagen Fluval Aquaclear HOB design).
However, with the exception of better media control, switching to a canister or two isn't going to do all that much for you. You might add a small canister to serve as a dedicated bio-filter (while still using your HOB's for mechanical filtration).

I agree with what you've found in your research.

125 - BGK, chanchito cichlid, pictus cats, silver dollars, palmas bichir
125 - cichlids (severums, bolivian rams, chocolate), rainbows ( turquoise, red), loaches (angelicus, zebra, kuhli and horseface), plecos (BN, RL and clown), denison barbs, tiretrack eel, pearl gouramis, betta
90 - Congo tetras, african knife, upside down cats, spotted ctenopoma, kribensis, delhezzi bichir
2.5 - betta

For African cichlid's which can average 4 to 6 inches as adult's,and their eating habit's,along with waste produced (depending on number's).
I would opt for canister which provides much more room for mechanical,biological media,more option's as to movement of water via spray bar's,lilly pipes, mounted nearly anywhere.
For small tropical tank perhap's one Eheim 2217.But for cichlid's,,I would purchase two of the Eheim 2217's.
They come packed with media ,and are reliable.Second choice would be Rena XP4.
Just my two cent's.

The most important medication in your fish medicine cabinet is.. Clean water.

really? Two? I have 1 2217 in my 72g with a powerhead and it's doing really fantastic right now but they are really young. So in all honesty you think a 2nd will be needed? I'm all ears as I find African cichlid advice hard to come by other then in fish store(which is good they do specialize is africans but also I love more then one sided opinions)
However for OP I agree that canisters are better for Afrcians but a proper powerhead is needed as well.

Oh and plants... Well the only thing surviving them so far are the banana plants. They even rip up the silk plants. Depends on the type of Africans you have..?? (If you name some I can tell you) but for the most part they will have lots of fun destroying your plants thats why I co for a clip with fresh Zucchini every day to keep their need for destruction fulfilled lol

Just popping in to say that any time you are considering the Canister route, two smaller ones to add up to the power you need is always better than one. It's a better safety net.

However I am not sure that you need two for a tank this size. Are the adults really that messy? You need to talk to an experienced cichlid keeper to find out what the adults bio-load is before making any major purchases with money.

Hello:
I don’t understand the need for two filters if one is all you need. Why would several filters not running at capacity or top efficiency be better? The filters might compete with each other for bacteria reducing the biological efficiency and creating ecology for bad bacteria to reside as well as reduced mechanical efficiency in both filters.
Are the currently developed filters so poorly designed that a back up is necessary fore the predicted failure of the fist filter.

Sang... Yes they really are that messy. Even as babys they are mind bogglingly messy. I'm supposed to see the Cichlid expert at my store today and I'll see what he says but I'm willing to believe as adults this is golden advice.
