Controlling Algae in Your Pond

Algae grows in the presence of sunlight when there are excess nutrients in pond water that algae then feed on. There are many sources of these algae-promoting nutrients, including nitrate, ammonia, uneaten food (which spikes phosphate), and excess fish in your pond compared to the volume of pond water. Other causes of algae presence include sludge build-up and lawn fertilizers leaching into the pond. 


All of these potential factors of algae accumulation beg the question: how can I prevent algae? Or if you’ve already noticed algae blooms in your pond, you might be wondering: how can I eliminate it? 

As always, API brand is here with your quick fix to all pond trouble you might encounter. To target and kill algae, we recommend API POND ALGAEFIX, which effectively eliminates green water, string and hair algae, and blanketweed algae to keep your pond water clean and clear. When used on a weekly basis, this product is also great for preventing algae, so your pond never looks unsightly.

API POND-ZYME SLUDGE DESTROYER is another effective tool for keeping algae at bay. Our powerful pond cleaner consumes pond sludge and breaks down dead algae, digesting leaves and grass clippings. Over time, this product helps to reduce your overall pond maintenance to keep your water clean and clear without any hassle. POND-ZYME SLUDGE DESTROYER is best used twice a week every two weeks to start and end pond season.

We recommend staying on top of your pond conditions to get ahead of issues like pond algae. A great way to do this is by testing your levels weekly using the API POND MASTER TEST KIT, which enables accurate measuring of the most common pond water parameters, such as pH, ammonia, nitrite, and phosphate. This kit comes with supplies to perform over 500 tests, making this a tremendous, cost-efficient tool for keeping your pond well-maintained.
