Not all ponds are alike! Your climate, your tap water, your fish load, the frequency you clean your pond, your pond's history, and more -- all of it make your pond totally unique. If you have been told or read that there is a magic bullet for your green water ailments... it's not true and potentially unsafe.
​
Plus, anything that clears your water fast is not addressing the root cause of the problem. First we need to determine why your pond is not clear and take care of that so that your water is clear for good!
​
If you are in our area and can come to our support center, please do so! Bring a water sample and some photos, and we can diagnose your pond issues and recommend the right course of action for your pond-- after all there is no one-size-fits-all solution.
5 Steps to Clear Green Pond Water
Step 1. Determine why the water is not clear
How you will clear your water is determined by what is causing it to not be clear. The Debris vs Algae photo shows that it is difficult to determine the cause by just looking at the pond -- they look similar. But once you take a sample of the water the difference becomes clear.
Do you have a single cell algae bloom like the right side of the photo? Then continue to step 2. If you have a debris issue like the left side of the photo, click the button below for advice. (Or skip to the bottom and grab our eBook.)

Step 2. Add Beneficial Bacteria
Although beneficial bacteria grows naturally in all bodies of water, in our backyard ponds it needs to be supplemented to keep the water clear. Beneficial bacteria works by breaking down nutrients in the pond and also competes with single celled algae for food essentially starving it.
​
Not all beneficial bacteria products in the market are the same. Our Cool Ponds BioClear and Clean is highly efficient and effective at keeping water clear. For existing green water situation, we recommend our Cool Ponds BioClear EXTREME, a live bacteria which makes it faster acting.
Step 3. Aerate your pond.
Although having a waterfall or a fountain is important for circulation, it doesn't count for aeration. An aerator pushes oxygen from outside the pond to the bottom of the pond. Beneficial bacteria is aerobic which means is needs oxygen to thrive and multiply. Adding an aerator ensures the entire water column is aerated not just where the water breaks the surface which you have with a waterfall or fountain. (As a bonus, they're great for deicing in the winter!)
Step 4. Use the right aquatic plants.
To battle algae, you need to starve it. The right aquatic plants will compete directly with algae for nutrients. In our experience, marginal plants (or shallow water plants) are the best long-term solution for competing with algae. Make sure you have plenty of them!
Step 5. Be Careful With Fish
There is nothing better than watching our fish cruise around our pond! And fish aren't the problem... we humans are. Our issues with fish cause so many green water problems! First off, don't let your pond get overpopulated with fish. Second, don't overfeed your fish. Third, make sure you are using only high protein fish food. Fish waste = nutrients in your pond = algae!
