As for sumps, they are really just for added water volume and a place to hide all the filter intakes, heaters extra, you could aways do a big wet/dry filter, as they are mainly a bio filter and then you could also run a conister for mechanical...
For the last time... Foam is predominantly a mechanical filter media.

I now know that I dont want a sump!!! which saves me a load of ballache and planning.
I am also happy to hear that all I need is 2 cannisters (FX5 & a large Eheim)
This will work out at £250 which saves me a nice amount... and I guess if it feel the urge I can always add another one.
I like the sound of once weekly or perhaps 2 weeks waterchange
Cant tell you how I dreaded coming home from work to lug buckets of water up and down the stairs every 2-3 days (depending on how much food my girlfriend fed the oscars when i was out as "they look so hungry...shame" hehehe)
aropal;1004240; said:Drip system meaning drip water changer. constantly changes water from mains flow in using inline filter media connected to dripper. Never lift another bucket. Excess overflows to drain. Of course you need to have a permanent connection between your tank and a water source and a drain but that’s not too tricky. Some people use pumps and stuff to run the waste to a drain and such but I wouldn’t bother with any electrickery if you can avoid.. You can create a dripper without any electrics and such a system is both easier and more reliable than manual water changes as well as being easier on the fishes.
Wet and dry and over head filter trays are terrible noisy and I wouldn’t bother with em, but I would reconsider a sump for an aquarium with the proposed 1700 litre volume that you describe.
This is true, but foam still is predominantly used as mech, as the surface area of fluval foam is very low, when compared to medias like bio-max, filstars, ehfisubstrat/substrat pro, or cell-pore.12 Volt Man;1003882;1003882 said:yes but nitrifying bacteria colonize the foam just like do any other surface.
they colonize activated carbon and ammo chips too.
the foam or floss is only primarly mechanical if you are constantly replacing it all the time.
if you are rinsing it and resusing it, you have lots of bacteria in there.
thats why filters like Aquclears that have just a foam block and carbon can handle bioload so well:
the bacteria live in the substrate just like they do in the more "traditional" biomaterial.
