Algae Reduction in Broad Run Ridge

We installed the Clean-Flo aeration system in March 2007 and noticed an immediate reduction of algae during the 2007 season. The algae coverage dropped from over 90% of the surface to about 60%. However, the real impact has come in there, our second season of usage. After an initial large algae bloom in late spring, the algae has disappeared. We now have less than 10% coverage, and this is limited to the shallowest, stagnant area of the pond.

Pond Restoration for Sun Ridge Association

With the steps taken so far, some amazing things have occurred. Firstly, the fish population has thrived. Secondly, there was a wild swan in residence the entire season keeping away any geese that tried to take up residence. But most importantly, the pond ecology is healthy, clear and can be sustained for much less. And best of all, they did not have to spend $200,000.

Bacteria Reduction in Lake Collins, NY

A Clean-Flo inversion oxygenation system was installed in late April go 2006, a significant drop in bacteria levels was observed after a week of operation. The systems turned off a few weeks after installation and bacteria levels rose. When the system was restarted, a decrease in bacteria levels was again recorded, suggesting that the Clean-Flo system was directly affecting bacteria levels in the lake.

Successful Restoration of Millersville University Pond

A few years ago it was observed that the pond was filling up with organic debris from the surrounding trees and taking on a murky appearance. Early in 2015, we had some fish die, and we knew we needed to do something quickly to remediate this situation. We first considered dredging the pond but the expense was high and the time to acquire permits would further jeopardize the pond appearance. It was at the time we were referred to Clean-Flo as a possible solution for our pond. Clean-Flo analyzed our pond water, designed the solution and had all the equipment in place in about a month. We are now approaching a year that the system has been installed and the pond looks great!

Successful Restoration of Lake St. Catherine

April 21, 2014

To whom it may concern:

We are pleased to provide this letter of recommendation for Clean-Flo and their lake aeration systems. We are a non-profit environmental association dedicated to restoring Lake Saint Catherine in western Vermont. We started working with Clean-Flo over five years ago when our research indicated that aeration might provide a solution for the shallower portions of our lake. Our working relationship has been quite productive, and our initial results show we are meeting our objectives.
The shallower portions of Lake Saint Catherine actually have many feet of organic material that has not decomposed due to an anaerobic condition. In places, we have four to five feet of water over a soft bottom with over 30 feet of this organic material to the hard bottom of this kettle pond lake. It took us several years to get a permit from the State of Vermont. Clean-Flo helped us prepare the design and the permit application, delivered the aeration system to our site and then provided technical advice for installation. The permit was approved in 2012 and initiated in August 2012. After one and one-half seasons we have had promising results.

The depth of the lake to the soft bottom has increased at each of the nine diffuser locations. The increases in depth at diffusers ranges from 6 inches to 24 inches. At the mid-points of the diffuser field, we have recorded an increased depth of roughly 6 inches. We have several control points north and south of the aeration field. No change in depth has been measured at these control points outside the aeration zone. We are pleased with these results and have recently received a permit to increase the number of diffusers from 9 to 13.
We are pleased to recommend Clean-Flo to organizations facing similar environmental challenges.

Restoration of Washington State Pond

September 12, 2009
From: Ron Harrison
Washington State

Dear Brian,
I have never written to endorse a product EVER before. If it were just the product, I probably wouldn’t take my time, but your professionalism, honesty and knowledge level made the difference. I know because I have been trying to clean up my pond (2,000,000 gallons) ever since I allowed Canadian Honkers to live here (’92 to ’97). I laughed at my PPD factor or “Poops Per Day” as they were running 300 to 400! These birds poop 28 times per bird with an average of 5 pounds per day. This would not be so bad, but 85% is nitrogen! (The U of W studied them.) I let them raise their young here until my trout tried to jump out of the pond because their skin was exploding. Unfortunately, it is all hindsight.

I called a water quality specialist and found the level of nitrogen and feces were off the chart. Starting in 1998 I used a competitors “concentrated” bacteria. I mixed it in 5 gallons of water and poured it in. I held the faith adding every year for a few years to no avail. After I had put up with that for about five years, I paid about six hundred dollars for an expert in 2002, and he used LLMO (Live Liquid Micro-Organisms). THESE were poured on the bottom with a hose. I held the faith adding a few times a summer for a couple of years, but the situation did not improve.

Starting in 2003 I used a competitors sludge busting microorganisms, bagged bacteria and compressed microorganism pellets. The bacteria was for the bottom, used by the square foot but sold by the cubic foot; I NEVER understood that. I spent and spent. Recommended was a pound per acre-foot twice a month! If the temperature of the water was below 68 degrees, double that! The warmer water kills trout, so it limited the time I had each year. It NEVER worked noticeably. I kept the faith for years, literally, hoping it would improve but the fish just kept dying, because I kept trying. The people I talked to claimed to be experts but just kept selling me anything they had really not concerned.

Finally, when the service got too bad I got fed up and got on the net and found Clean-Flo. I liked the philosophy of different types of bacteria for the bottom by the square foot and water column and filament strains by the cubic foot; it made sense. You would not let me buy as much as I wanted. I had never heard such a thing before.

Then WOW! In the FIRST Spring and Summer, I saw significant improvement. The milfoil I managed to hold down with expensive blue dye with a special yellow dye to stop photosynthesis has just disappeared, IN ONE SEASON!! C-flo ate the floating feces I had FOR YEARS! C-flo, C-flo-6, and C-flo-6F are truly a wonder. This year with the C-flo .family I am in shock and awe at the results and the low price. Not only cheaper but actually worked. It is a pleasure to look at the water and see it sparkle! I have not seen the actual gravel bottom for years. WOW again.

I highly recommend you and your amazing products. If you couldn’t have helped you would have said so and that cannot be said enough, it is a rare quality. I wish I had found you sooner, but I am just glad it didn’t take any longer.
