Power head flow rate

[Fishfinder1973]

Has this ever been discussed on the forum?

I don't think we need to wait til the fish are being swept away before knowing when it's too high a rate.
Would be interesting to find out opinions on the subject.

Yeh all depends on the fish. And as you say, it can be very obvious with some, whether they're struggling to maintain normal swimming behaviour. Seriously fish often states their natural habitat and if the waters are calm or rapid. Weather loaches for instance, are found in fast flowing waters where they'll latch onto rocks. Betta's are found in still water, puddles pretty much! I think even for the fish who enjoy a bit of movement, it is good for them to have a buffered area where they can have a rest from time to time.

I do like the stream setups.. would be a bit noisy in the living room though!

You can slow the flow by fixing a sponge on the outlet, you can if you want to use a drink bottle cut filled with wool to polish your water fixed to the inlet, just make sure you put a fine net on the inlet the suction is very strong it will suck small fish in as I found out.

This topic is frequent on the forum, in connection with any filter issue, as flow is always a primary (or should be) concern for the filter. Different fish have differing needs when it comes to the water current, and that should be the deciding factor.
