Product Overview

Easy assembly in only a few minutes.

Compatible with Any Aeration Compressor over 1-CFM.

NO Membrane - NO Extra Backpressure!  The original High-Efficiency Diffuser from U.S. Solar Mounts, the DB-36 showcases why our diffusers are a step above the rest.  These diffusers utilize extruded EPDM Fine-Bubble tubing and all-stainless bases and hardware instead of industry-standard rubber membranes on plastic or coated-steel bases.

100% Made in USA!  Each diffuser is ruggedly constructed using high-quality, American-Made components.  The bolt-together package is quick and easy to assemble and requires No Fill!  A built in handle, tagline loop, and dual-size hose strain relief clamp make this a truly premium design.

Compatible with 3/8" or 1/2" ID Hose.

Ships with a 3/8" Hose Barb installed and 1/2" Hose Barb included - Simply change the barb fitting for 1/2" ID Hose. Can be easily adapted for other hose sizes as well.

LIFETIME WARRANTY included on all diffusers.

    Best I've dealt with

    Posted by Thomas Donley on 12th Jul 2023

    You folks are absolutely the best on-line business I've ever dealt with! Within 3 hours of ordering, I received notification that UPS had received the product I ordered and had it in transit already. That, without doubt, is truly rare and exceptional customer service! Having previously purchased one of your diffusers from a local supplier, I can also affirm that the quality of your products far surpasses those from all other diffuser manufacturers. Thank you for the integrity this organization brings to it's business operations, and rest assured that every pond-owning friend I know has already been shown my two US Solar diffusers, the DB-36 and the SB-24. All agreed that they are superior in design, quality and performance to what they are currently using so, hopefully, I've drummed up a little more business for you folks as a way of expressing my appreciation. Thanks again, Thomas Donley

    Best Diffuser I have ever owned

    Posted by Richard DenUyl Jr. on 30th Jun 2023

    Every diffuser I have purchased in the past has been made of plastic and breaks within a year. This one is top quality. It sinks right side up and it has a protector so the water line attachment does not get stressed and crack off. It also produces way more bubbles in my pond that other bands.

    Lots of bubbles, lots of surface agitation.

    Posted by James T. on 30th Jun 2023

    After a strong cold front hit during summer-like temperatures a couple of weeks ago, we experienced a rapid turnover that caused a major fish kill in our 1/8 acre pond. The aeration system needed a revamp, so we decided to try something different. I went with this diffuser, vs. the round rubber membrane type we used to have, as I was never completely satisfied with how it moved the water on the surface. Not only does this unit make a lot of bubbles, it moves the top of the water much more vigorously than the previous unit did. We have a couple of small coves that didn't see much movement before, now we are seeing waves make it all the way to their shores. The stainless steel base is very sturdy, and much less cumbersome to maneuver than a plastic box full of gravel. The design of the diffuser ring makes a thick column of small bubbles, along with good surface agitation. I am very pleased with this purchase.

    stainless steel wont harm fish

    Posted by Amazon Customer on 30th Jun 2023

    At first I wondered why they were so expensive. But being made out of stainless steel there won't be a reaction with the water and if you prize your fish like I do I don't want to harm them in any way. Do yourself a favor and keep any aluminum or iron or any other metals except stainless steel out of your ponds .

    Works Great!

    Posted by Debbie Weir on 30th Jun 2023

    I ordered this, the HiBlow HP 80 air pump, and 3/8" self sinking hose. I installed it this past Friday, June 2nd, in less than an hour (still need to bury hose under deck in PVC). First picture was taken Friday after installation, 2nd picture is Saturday morning, and last picture was taken at 9 a.m. today. Coudn't be happier! I did skim out some of the algae yesterday as it was clumped up at the shoreline later in the day. FYI, my pond is just under 1/4 acre and its depth runs 5 ft to 10 ft.

    Excellent Diffuser

    Posted by Larry on 26th Jun 2023

    After years of replacing diffusers due to lack of durability and performance, I chose the DB36B for my 1/4 acre pond. Received it and was very impressed with the quality, easy assembly, and effective performance. I might even add a second one after seeing this one. Best of all - Made in USA! Great design and should be effortless to maintain.
