I would suggest that an inline pressure accummulator tank and a valve to your aerator stone would be a wise move if you are using a fridge compressor since they are not designed to run continuously. Also, since they are free it may also be wise to hook up several to a "manifold" leading to the tank. It is then a simple matter to hook a pressure cutoff switch to the tnak and use it to control the compressors on/off cycles. Iff one poops out (and you notice) replace it with a spare. We used small dia. rubber hose slipped over the outlet tubes and secured with hose clamps connected together with inexpensive plastic "tees".
