Arowana filtration Question

[bitteraspects]

you would need some bigass powerheads. hahah.

most of the asia keepers i know (mostly guys from SG) use a single submersible pump in the bottom of the display.
you might be able to get away with powerheads if theyre big enough, but it will put strain on the motor.
(most) powerheads are rated at 0 pump head, and are not meant to pump water vertically, and the head pressure created by pushing the water above the display can wear the impeller overtime.

yea like for me ive been using internal filters cause they are the easiest to get,the filteryou mentioned earlier is.........confusing looking xD.I have a 20W internal filter which isnt being used.I was wondering if it would be enough for filteration for a 4ft arowana tank.(BTW it came with a sponge as its media but I lost it when i was packing it up but now if you guys think its usable for the tank i mentioned above , what sorta media do i put in it ? do i stick with the sponge ?

internal filters dont really do much IMO. they can provide some biological filtration, but they dont do anything for mechanical filtration. not to mention, most of them are ugly and bulky.

OHF filters are not really that confusing when you get the hang of it. theyre actually pretty basic. you have a pump in the bottom of your tank, it pumps water to a tray above the tank where it flows over a mechanical filter pad, and through some bio-media, then back into the tank. they hev stackable OHF trays, and even complete setups available at most LFS in asia.
where in malaysia are you?
you should try asking around your local shops or arowana farms. they should be able to give you some more info.

Im in Kuala Lumpur.But if I use a OHF wont that mean that there wont be a lid on my tank ? and most LFS with arowanas ( like alot of em) they use internal filters.This is what made me confused whether they were the perfered choice xD . i guess i was wrong :/

many LFS use internal filters because they are cheap. also, they do frequent water changes (every few days) to keep the water clean.

you can use a cover with a OHF. the trays sit towards the back of the tank, so you can make (or possibly buy) a cover for the front.

Darnit i thought I would be able to use a internal filter
Cause im only 15 but my hobby is rearing fishes which I hv done successfully for the past few years.I used an internal filter with my baby jar I had last time and it turned out fine though [ but it ended up dying due to parasites ]

Time to go Filter hunting xD

if its all you have, it will be ok for a little while, but you will definitely need to look into upgrading to an external/canister/HOB/sump/etc ASAP

I think i will stick to an internal filter temporarily.( maybe for 5 months) i will still cycle the tank and all that.do u think is hould fill the cannister with just 1 block of sponge ( like what it came with) or should I buy the different media and fill it ( im affraid it will get clogged or something)

I'm running a Fluval 4 plus and an old Fluval 4 in a 4' growout for a juvie Silver. As some have mentioned, they don't do much for mechanical filtration (poo everywhere), but I do 25% water changes, ammonia and nitrate checks and clean up the tank weekly.

Use what you have for now if you can't upgrade, and look at getting externals/canisters or a sump set-up for when you have the means to.
