i have an aqueon 75 quietflow in my 36 gallon but I dont think my swordtails like the current very much. Would putting a sponge over the intake help slow it?

It could but only do so by clogging the filter. You can instead try to redirect the flow by making and attaching a shelf under the outtake, having the water ripple the surface more instead of plunging deep into the tank. Raising the water line will also help.

I do this all the time with my low flow fish like gouramis.

You can put a sponge in the filter out flow, or you could direct the out flow at a tank wall to let the friction remove most of the water speed!

I have pre-filter sponges on the intakes of all my Quietflow filters.

The only time it slowed the flow down was when the sponge (Fluval Edge pre-filter sponge) became clogged and affected the intake of water.

Yeah on my penguin 170 it made a lot of flow and it made so much noise so I just stuffed a standard filter cartridge into where the water comes out
