Wait for a minimum of 3 days between treatments. Repeat dosage once per week for maintenance. Use With Aeration Before using Algae D-Solv, make sure your pond has vigorous aeration such as a fountain, waterfall, or aeration device. Without aeration, your fish may be at risk due to decreased oxygen levels, especially during the warmer months. Variety of Applications Ideal for fountains, self-contained aquariums, backyard ponds, lined water gardens, and decorative ponds without any outflow. For best results, remove excess algae prior to treatment. FAQs Does Algae D-Solv only work on string algae? Algae D-Solv effectively controls many different types of algae, including green water algae, string or hair algae, and blanketweed. Algae D-Solv offers fast-acting, broad-spectrum algae control. Does Algae D-Solv work without aeration? It is recommended to use Algae D-Solv with aeration, such as a decorative fountain, waterfall, or bottom diffused aeration. Aeration must be continuous. During warm weather with high water temperatures, vigorous, 24-hour aeration is required. High water temperatures cause more rapid decay of dead algae, which can cause fish distress. When algae is treated, it may cause oxygen levels to drop to harmful levels if adequate aeration is not provided. Will this algae remover harm my fish? Algae D-Solv can be used in ponds that contain fish. Always use in accordance with the label directions. Do not use Algae D-Solv with snails, shrimp, clams, and other crustaceans or mollusks. Can I get rid of algae without hurting my water lilies? Yes, Algae D-Solv will not harm ornamental plants when used as directed. How much Algae D-Solv do I need? Use 1 ounce of Algae D-Solv per 360 gallons of pond or fountain water. Pour evenly around the pond edges or into an area with the greatest circulation. Do not use more than the recommended dose. Wait for a minimum of 3 days between treatments. Repeat dosage once per week for maintenance. Maintain a Clean, Clear, Thriving Pond Algae D-Solv easily controls algae growth and reduces pond maintenance, so you can get back to enjoying your pond!

Review: It worked, it really worked! With one caveat. - This was recommended to me to The Pond Guy. We had some extensive work done on our pond this past spring, and the people who did the work also said they’d clean our pond… they used a pressure washer. A real no-no, as the spray is too harsh and washes off all the ‘good algae’. A plain garden hose would have sufficed and been far better. Anyway, flash forward 8 weeks and I had the worst string algae ever. So thick… I used a stick to pull up globs every morning, and that didn’t touch the issue. It just got out of hand. Our pond is small – only 500 gallons. I used 1-1/2 ounces - first I cleaned a bucket very well, then dipped it into my pond and collected a bit of pond water. Then I added the Algae D-Solv to the pond water, swished to mix, and gently poured it into our pond. I repeated this every 3 day, for a total of 3 times. After the 3rd day of the 3rd treatment (12 days later), there was NO string algae. None. Of course, throughout the treatment I did have to clean the pond, the filter, and skimmer daily. Also, I have 2 falls, and added 4 bubblers while I treated the pond, for added aeration, which helps. Unfortunately, it left my pond very turbid. I couldn’t see the fish, or anything. Tried water changes – several. Added beneficial bacteria (unnecessary). No help. Finally ordered CrystalClear RapiClear Liquid Flocculent – one treatment did the job. After that, I occasionally treat the string algae, once, which does the trick, and several days later add the flocculent. I have comets and shubunkins, and because I know my pond’s correct volume, they were never harmed, nor were my water lilies, hyacinths, or other pond and bog plants. I also had a couple comet fry, and they are fine. Not a fan of adding anything to my pond. I'm a big believer in letting nature do it's thing. But sometimes the pond needs a bit of human intervention to keep it healthy. UPDATE: The weather has cooled off here, and this product does not work as well in cool/cold weather, BUT it does work - you need to give it time. My string algae started to return so I did 3 treatments, adding the D Solv every 3 days. After the 3rd treatment I just gave the pond a few extra days and sure enough, it's totally clear of string algae once again (average nighttime temps are in the low 50's and I've stopped feeding the fish, of course).
Review: It just works - This is really a great product. When used as directed, it does kill string algae. Be sure to follow the directions.
