Two Filters?

[sXeLifer]

Right. So i have 2 filters one at either end of a 110L/30Gal. Is this going to make a difference to the water quality. I have one big filter that is good at "filtering out the crap" and another that is good at breaking up the water surface and introducing oxygen to the tank. So which one do I really need.

Cheers

I ran 2 filters on 200L at one stage, and although the first filter was more than capable of keeping the water clean and providing a decent turnover, I did find that with the second my water was crystal. However, I would say it wasn't a necessity to have both on mine. If your first filter is a doing a good job at sucking the rubbish out, then thats good, can you not place the out-take of that one nearer the surface to create movement? What I did for my other 100L tank was have one external running and placed a small koralia 1 powerhead at the other end to create some movement.

I keep 2 filters in my 55ltr now as I can get another tank up straight away in an emergency. I'm not sure how much difference it makes to the water quality though as one of them is only a small filter so I just leave it there as it's reassuring to have a back up.

I run an internal and external on mine. My larger external could easily handle the waste for the tank, but I've kept the internal going to increase flow for the plants and also to aid surface agitation.

It's up to you really.

That will really depend upon what two filters are currently running.

Your loaches, like many in the Botia genus, do appreciate oxygen rich water and good water quality, so a moderately rippling water surface from 600-800lph of filtration (800-1000lph marketing, filter will lose at least 10% through real world use) in your 110l tank.

Incidentally, your Botia striata group (hopefully 5+) will probably need a tank upgrade as they get older and bigger, to a 4-foot long tank.
