Fluval C2 or C3, Oversizing For Tank OK?

[JohnRoscoe]

I have a 16G bowfront that I've decided to trick out, rather than investing in a larger tank now, will eventually upgrade though, and would like to reuse when I do.

The Fluval C2 is listed for 10-30 Gallons, and the C3 is listed for 20-50. Could I use a C3 with the flow rate turned down in my tank, or would it be too much movement?



Also planning to switch to buried cable heating and considering a bubble wall at the rear while I have the tank torn up, don't think this affects the filtration.

i would go with C3, no such thing as over-filtration. as long as your fish is not been blown out of the water, it will be fine.

Yah, i would def go with C3. Its only a few bucks more. That way when u ever upgrade it good to up to 50G. If its too much current even on the low setting, you can always slow the flow rate even more by putting a sponge filter or something at the spout of your filter, or add some cool floating plants. I added floating plants, and it helped till my fish destroyed them.

Thanks to both of you. A C3 it is.
