    Excellent product, Excellent service

    Posted by Steve on 17th Sep 2020

    I ordered four of the DB-36 diffusers. The product is rock solid and they really move the water. They came well-packaged and without any damage. The customer service from Eric was outstanding. The diffusers are very well made. Will definitely be doing business with US Solar Mounts again.

    Best Diffuser on the market!

    Posted by Jon M on 29th Jun 2020

    My wife and I have a 2.5-Acre pond. We originally purchased an aerator package online that included diffusers with plastic bases that we had to fill with pea-gravel to sink them. After a few years, the plastic fittings failed and we needed replacements. We purchased several of these diffusers from US Solar and could not possibly be any happier. The company was great to deal with and talked with us before the purchase. The diffusers are really, really well-built. The main assembly is ALL STAINLESS STEEL and is actually welded together! They move a noticeably higher volume of water compared to the disc-type that we used to have. Our compressor seems to run easier as well. Great Product! Would highly recommend this company!

    GREAT DIFFUSER - Very Well-Built

    Posted by Thomas H. on 1st Apr 2020

    Ive installed a lot of diffusers for customers (and my own). This is hand-down, by far the best-built diffuser on the market today from any company. We have installed a few of these units so far and they work great at various depths and different air flow settings. No plastic parts like many of the others out there. We did have to change the barb fitting since we use a lot of 1/2 air hose.

    Im really pleased with this diffuser. It is just as described: solidly built, self-righting and easily installed. It will last for a loooong time. Now, my koi have the proper aeration they need to combat algae and parasites!

    US Solar Mounts DB36

    Posted by gornr on 8th Feb 2020

    The product has a robust design and build quality (stainless). Im limited to 6-FT depth for diffuser operation in my pond due to the spec limits of the air compressor Im using. The diffuser can be located in much deeper water. I bought two of the diffusers to increase the amount of dissolved oxygen added to the water due to significant muck build-up after about 35 years. Mr. Pipkin provided excellent support and was responsive to my questions regarding operation and installation.
