Tetra EX20 Filter to Strong!

Ok, i have a 10 g tank with a ex20 power filter. As far as i know, there isnt a control for the flow and it seems to be blowing my fish around and there food. What could i do to slow the flow down? Ive tried using a coarse sponge, but it either stops the flow, or it gets clogged and then if it does work, it will push it through within a day.

In other threads, members have mentioned making a diffuser or baffle for the filter outflow; the sponge should be over the outflow, not the intake into the filter, and it shouldn't clog on the outflow as the returning water is or should be clear.

Filters should be geared to the fish in the aquarium; some require a current, others definitely do not. The latter (fish like most of the characins, angels, discus, gourami, rasbora, Corydoras) can become quite stressed by having to constantly battle a strong flow, and stress leads to health issues. If you have fish like these, I would consider replacing the filter with a simple sponge type if you can't somehow eliminate the current. You don't mention plants, but they also do best without strong currents.

I am not sure about the sponge, the intake flow has to be slowed down. It is hard to stop the return if the intake is still flow flow. I do have a Tetra PF10 and the flow is good.
