Reducing External Filter Output?

[Kipper_Face]

I am in the process of setting a quarantine tank (10 imperial gallons) and wondering if its possible to use an old external filter instead of buying a new internal filter?

only problem i can see is that the filter has a turnover of 103 gallons so would need to reduce it considerably. Any suggestions gladly accepted. (filter is an old fluval 103)

Also anyone suggest a cheap shop that sells 15 inch x 1inch tubes for tank lighting in the uk, i thought maybe B&Q (white tube is fine as i aint growing plants in it )

The HOB filter I am using on my 10 gallon does about the same gallons per hour, but it does have a knob to reduce flow that I sometimes use. perhaps you can just get an adapter to reduce the size of the hose little, that would reduce flow?

Why would you need to reduce filter turn over?

What ringham is saying is that, overfiltration is not a problem. If it is the amount of current you are worried about then you could always put a spraybar on the return hose. It's basically a long pipe with a closed end with a bunch of smal holes all along it. That way it redirects the water flow.

failing that you could take the simpletons approch and cover the end particaly but i wouldnt advise it if you can get a spray bar/equivelnt

i have a spray bar but would 10 times the volume of the tank per hour not be overfiltration? seems alot for such a small tank?

I know I "over filter" but in my 10 gallon, I have a Whisper 30 - rated at 150 gph - that is 15x filtration per hour. I do turn that one down a little ususally.

In my 29 gallon, I have a Aquaclear 70 - rated at 300gph, over 10X filtration. As long as the fish don't mind, I think it is OK. Some fish, like Betas for example, don't like current much.

ok, i will go with it. saves me cash and does the environment some good by recycling an old filter! B)
thanks for the replies.

You generally want to aim for 5 times per hour anyway, so 10 shouldn't be too much of a problem. a spray bar pointed upwards at a the glass side should reduce the flow as well.
