I use a canister filter with a spray bar with my ACF, it has decent flow but not over powering. I haven't had any issues what so ever.

African Dwarf Frogs like Tony mentioned, are really poor swimmers and are prone to drowning when the water has too much current or water levels are too high.

ACF however, are incredibly strong swimmers, they -prefer- stagnant water but having at lease some flow is healthy for your tank. When I put my spray bar against the glass to reduce flow I started to get blue green algae aka cyanobacteria which is not something you want... :/
