Review: Lots of air! - Works great! Hiblow Pump The pump itself is very quiet and silent from 20 feet away. Easy to set up and comes with the rubber adapter and clamps to hook the pump to a 3/8 inch air line. Filters and parts for the pump are easy to find so down the road any maintenance should be very simple and that is why after many weeks of research I decided to purchase this pump. Running my system 24hrs per day with no problems and do not expect to have to do anything but clean the air filter every 6 months. My Setup Hooked to 1 12” Matala diffuser and 1 Rootscape large hose style diffuser. Running 100ft of weighted 3/8 air line. Diffusers are set down at 8 ft and producing nice boils. (Soon to be 2 Matala 12" diffusers) Air Diffusers My personal opinion on air diffusers is the Matala 12" produces high quality fine bubbles and the Rootscape produces larger less effective bubbles with smaller boil size and less water movement. I just ordered a second Matala 12" diffuser to replace the Rootscape. If you plan to use this for a pond or saltwater canal application my advice is to go with a membrane style diffuser such as Matala. After just 24hrs of running the system my water is clear, no more smell, and I have seen much more fish activity.
Review: Reliable, cost-effective alternative - When my septic system's aerator pump died, I was unable to procure the same make and model (Retailer was of no help and the Distributor wouldn't deal with individual customers). This pump spec'd the same, it runs quietly and has been doing so for more than one year. Added benefit; it costs significantly less.

Use this for pond aeration. 12" Diffuser is 8 ft down on a 50 ft 5/8" weighted air hose. Works great and very quiet.
