What would be currently the most recommended set-up with Profilux controlling an external third-party automatic feeder? I would like the idea for the two to work together... e.g. Profilux slowing down the pump to lower the water current, activate feeder and then after some time bring the pump back to full speed again... Any way this can be done with Profilux 4? What would you recommend as a good feeder to use like this?
