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: Good Algae Control Product - I put a dose in my pond every Sunday and I don't have algae problems. Works perfectly.

## Questions & Answers

**Q: My rocks are still covered in algae after two applications: any tips?**
A: When using CrystalClear Algae D-Solv, make sure to clean the excess algae off the sides, ornaments, and rocks before adding this product. This will reduce the amount of decaying organic matter.  Also, you will get the best results using this product in conjunction with vigorous aeration and then following up with beneficial bacteria.

**Q: Is this product safe to use on water features that attract birds?**
A: Sorry don’t know. Ask manufacturer

**Q: How much for a 300 hondred gallon pond**
A: Dilute 1 ounce of CrystalClear Algae D-Solv for every 360 gallons in a container of pond water. Pour the solution into the pond in an area with the greatest circulation. You will see the best results using Algae D-Solv in conjunction with vigorous aeration.

**Q: I just have a small fountain, how much should I use for 4 gallons?**
A: Guessing teaspoon.  A small portio you’d use in a koi pond. Read instruction. Use a small % of that. We have 2 koi ponds 4x16x2 feet and 4 ft wide and 2 feet deep x 22 feet long.
