im just wondering if i use the Martin Thoene River-Tank manifold but have double the amount of sponges on the end will i A: increase the bacterial effect the sponges have , or B increase the flow. i will be using 2 900 lt/h powerheads and 15mm piping.
thanks

I would think that it would probably do both. It would also take up extra room in the tank.

Cheers jim for the reply. Size isn't to much of an issue as I've got 6x2x2 to play with.

hehe nice. Perhaps add a wavemaker in between the powerheads for added circulatrion

i was thinking about that ClownLoachSharky esp as fleabay has them for 7 euro at the mo!i found a third 900lr/h powerhead i forgot i had so i could use that but the wavemaker might be better for sheer volume of water in the tank.
im still unsure if i should use the 2inch hole drilled into the side of the tank and sump the tank or just run a spare external i have

Add the extra sponges. The nitrifying bacteria appreciates a good water flow, but too few sponges means the water may be moving too fast through those sponges. Also, fewer sponges means they will plug up faster between cleaning.
Something like a wall of sponge might be a good way to go, since you have the room.

cheers diana, im using 4 6inch by 2 1/2 inch sponges on the end of the manifold but can double it by raising 2 sets of sponges between the original pair (4)

A sump refugium would be nice. Considering that loaches uproot many plants.

Didn't think of that clownloachsharky but a do recall reading about them somewhere lately. I suppose I should find out what size sump would be ideal for a 6x2x2ft tank.
I got the tank into place last night after having to lower the cabinet i made for it, so i took the opertunity to
tint ( car window film) the back and 'seen' side. The window side is painted chalk board black.

thanks for the links they helped a lot........ except for..........

my tank is drilled (2 1/4 dia) abour 6 inchs from the top, and i only have 9 inchs between the tank and the wall to get all the sump pipework in.
As this is the case it seems im going to have very little room for thesump pipework, but if im correct it could go like this:- inside tank.... up turned 90degree bend joined to bulkhead fitting joined to a sideways T fitting, and a ball valve (tap) then into the sump with the outlet being under the level of water in the sump. i suppose its an external durso standpipe.
would i be correct?
