IF YOU NEED TO AERATE REALLY DEEP WATER THIS IS YOUR SYSTEM!
Capable of pushing air down to 90' deep, this system can handle high pressure caused by deep water or long airline runs. Powered by a 3/4 HP piston compressor, this kit includes three air diffusers, compressor, valved outlet with brass valves, 600' of non-weighted tubing and all fittings and clamps. Compressor is available in 115v or 230v (please specify when ordering), amp draw is 9.5 at 115v and CFM air output is 5.1.
Spare Me! Keep a spare air pump or water pump on hand for emergencies. If your pump ever stops, do not feed your Koi.
Consider using seperate water pumps for your waterfall and filter. This way you will always have a backup, and you can save energy.
