My HP-100LL has been running 24/7/365 for three years with absolutely no problems!! Prior to installing it, my farm pond would develop a large amount of algae by midsummer. I did some research and discovered the best way to get rid of the algae was to aerate the water. I discovered HIBLOW by watching other people on YouTube constructing similar DIY projects. Three years later, my pond is looking great and I couldn’t be happier with my with HP-100LL air pump. The only maintenance that I’ve done on it is to change the air filter. Recently, after three years of non-stop running, I thought I should replace the diaphragms as preventive maintenance. I contacted HIBLOW and Mike quickly give me the part number for the kit that I would need. He also found me a nearby dealer that offers free shipping. Afterwards, he informed me that it’s not unusual for the diaphragms to last up to 5 years, sometimes more. He suggested that I replace them after they fail. He told me that no harm would come to the pump once the diaphragms failed, because of a built-in safety switch. Thank you for the great advice!
To anyone looking for a great air pump for your farm pond, I highly recommend HIBLOW’s long life (LL) air pumps!
Here’s the video that got me started three years ago:
Lastly, I would like to thank St. Isidore’s Farm for taking the time to make a video on DIY pond aeration. You’ve saved me a lot of money! Thank you.
