My main concern with this system is the underwater weighted airline. IMO it is undersized for diameter at 3/8". However this pump that produces at least 25psi (50ftdeep) rating. Airline of 3/8" ID for rocking piston will work but I think it would better perform with 1/2" or 5/8". Long term the for life of the pump larger dia airline would be better for less stress on the pump. Mechanical stress is what wears parts out. The Vevor company website gives more options. Contact them for if larger dia airline is available or ask to buy the system without the airline then buy airline somewhere else.
