Biological augmentation
Muck is the soft layer of organic matter that settles on the bottom of a pond. It builds up from leaves, dead algae, fish waste and grass clippings. Breaking it down uses up oxygen. When the bottom water runs low on oxygen, the sediment can release phosphorus, and phosphorus feeds algae.
Biological augmentation means adding beneficial bacteria, enzymes and micronutrients. They support the natural microbes that break this material down. Those microbes need oxygen to work well, so we often pair treatment with aeration.
We are honest about results. Independent studies are mixed, and bacteria alone will not fix a neglected pond. It works best as one part of a plan that also adds oxygen and cuts the nutrients coming in.

What it does
- Supports the natural microbes that break down bottom muck
- Works best with aeration, because those microbes need oxygen
- Pairs with nutrient control to cut what feeds algae
- Needs repeat treatments to keep working
- Checked with readings so we can see whether it is helping
How it works
- Test and inspectWe check oxygen, water clarity and conditions on the bottom before we treat.
- Build the planWe match the treatment to your water and add aeration or nutrient control where it is needed.
- Treat and monitorWe treat on a schedule and take readings at each visit to see what is changing.
- You get the recordBefore and after photos, readings and products used, by email and in your client portal.
The science behind it
The muck on a pond bottom is organic matter being broken down by microbes, and that work uses oxygen. When the bottom water runs out of oxygen, the sediment can release phosphorus back into the water and feed algae. Aeration keeps oxygen in the water and helps the natural breakdown along.
Adding bacteria and enzymes is meant to support that process, but independent tests are mixed. That is why we use them only as part of a plan with aeration and nutrient control, and track readings to see if they help. Where phosphorus is the problem, binding it directly can work: in a study co-authored by SePRO's Dr. West Bishop, a lanthanum clay treatment removed over 80 percent of phosphorus from the water in two weeks and locked sediment phosphorus away.
This is why we hold the Arizona Lake Symposium every year, with PMD CEU training credits. We use the science and apply it to what we see and measure on your water. No canned plans from a desk at a distant head office.
