reducing current?

[id10t]

I recently got a couple of killifish for my tank, and they are really cool. However, they aren't a big fan of the current my filter produces - its a biowheel, came with the tank (10gal). I turn the filter off for a few hours and they are much more active and happy looking, with the current on they really just hang in the back upper corners...

So.. any tips on reducing current? I'm thinking I'll need to redirect it and slow/diffuse it - a sponge maybe on the output??

Thanks

adjust the flow on the filter it self.. what type of filter do you have?

Penguin Biowheel... only apparent adjustment is to move the intake tube up/down into/out of the pump housing, doesn't appear to affect current....
