I have the pat mini filter powerhead with a double sponge air filter attached. The central pipe was a good fit for the opening of the powerhead. I heated and crimped some airline to put on the airline nozzle to block it. The sponges are really dense. You can even buy the double filters with a media basket if your tank is
deep enough. ‘
The tank is dirted and was setup as a ‘Walstad’ experiment with a just a light but the temperature was dropping to 12c at night so a heater and powerhead were added. The air filter mod only cost £6 and gives lots of sponge for shrimps to pick at
