    Hi

    So i have a question with regards to filters...

    If I have a 3 to 4 foot or equivalent sized tank what kind of filter is advisable. I don't want to do a sump. I have read that with a good clean up crew under gravel filtering is not needed. So will en external filter hanging over the side do the trick?

    I appreciate any advice on what a suitable solution would be for this setup, bearing in mind i dont want to spend an arm and a leg. The tank will have LR, 8 or so fish and a coral or 5

    Cheers

    I think a nice sized canister filter would be better than a hang on if you have to go that route. It would be easier to modify or add filter material to.

    And a skimmer.....many options for hang on skimmers.

    So the canister filter sits inside the tank?

    Why are you against a sump if I may ask?

    Canister filters are external ie not inside the tank

    I'm no expert, but a sump has quite a few advantages over a canister. Biggest ones in my opinion is the filtration space when compared to a canister and additional water volume that the sump adds.

    Won't you also need to do a lot more regular water changes with a canister?

    If the canister filter is outside the tank, how does it cause the tank to have less water volume as opposed to using a sump ?

    a sump will cost you a little more than a caniter filter and the benifits far out weight that of a canster.

    -increase water volume
    -less maintenence
    -more sability of water parameters
    -hide most of the equipment like heater in the sump.

    No Rakabos - the canister filter sits OUTSIDE the tank.

    I did not get the jest of your tank - do you indeed (or not) have a sump?

    A sump allow you to have all equipment out of the display tank. Such as heater, skimmer and filtration. It is also less maintenance than canister as you do not need to change filter media - the DSB does the trick in stead of a canister filter.

    But there are people not using a sump. So everything is in the display tank: heater, hang on skimmer and hang on canister filter.

    I am in the process of getting everything for the tank and looking at options for filtration. A sump is a hassle to put in place but less maintenance in the long run it seems?

    Sumps are generally a lot bigger than most canister filters. Bigger = more water volume

    Ok so if the filters hang outside the tank, the only thing taking up space in the tank really is the heater(s) ?

    And undergravel is so yesterday - as my kids will say.

    The technology moved on. But you do not have to spend an arm and a leg to achieve the target idea of the technology.

    Plain and simple 3 chamber sump. But Skimmer is a MUST. A Reeftek TS1 or similar should be nice. Then a DSB and your return pump.
    Plain and simple.

    Overflow box, new slimline design, takes less space in the tank. Return, standard over the top loop with siphon break.

    So what is the extra layout?
    Glass for sump
    Skimmer - a must anyway if you go hang-on anyway.
    Return pump.
    And some plumbing.

    Well Liferock you anyway have to do, both routes. So let us leave that outside the picture.

    8 fish at about (if you go average and no really expensive fish) R200 each. And you invested R1600 on fish only, no corals, zoa, leathers, softies or anything else yet.
    Extra hardware needed will be less than the fish you want.

    And once you got it, life / reef keeping will just be simpler.

    It is the same as having a battery in your car. You do not need it really, you can push start your car every time... Just make life a lot easier having it...
    (Had to push start my car enough times last week to really appreciate the things making life easy.)

    Lol

    Thx for the info... Most of what you said is pretty greek to me with regards to the standard over the top yadda yadda... Its also part of the reason why i was thinking canister filter / skimmers. It's much easier for a noob. So maybe start off this way and then do a sump later when im more confident?

    Do sump from the start. A cannister for 250L will cost you R1200+, you will be able to do a sump for less than that

    Thx guys...

    Seems a sump is the way to go. Do things once and do it right i guess. Now to do some research on a sump. Is it easy to DYI? And what is the minimum size i would need for a 4ft Display tank ?
