Review: Good Product - I purchased this product on the recommendation of the professionals who installed my pond. Be advised, to clear a severe problem of algae and sludge, the product does not work unilaterally. it must be used in concert with an accelerated maintenance program until the problem has been brought under control. For me that meant cleaning out my biological filter every 3-4 days and changing out the leaf basket regularly in addition to using this product. After about one month, the water in my pond was crystal clear. I actually started seeing results after the first week. With a weekly application of Clarity Max, I have been able to maintain my pond in this clear condition. The product has worked well for me. I've since ordered a 6 pound size which at my current consumption rate, should last well over a year.
Review: Finally a Real Remedy for String Alage!!!! - I find it interesting to read anything but a 5 star review of this product. For me, I tried many, many products to clear my pond of what I would call severe string algae. Even a couple of pond professionals who came to my pond told me I would have to just live with it. My pond has constant exposure to direct sun and very high pH - two things apparently algae love. I had all but given up when a guy at a pond store swore this product would work. My algae problem was so bad that I was desperate enough to try it. I am so glad I did!!! It made a huge difference almost immediately!!!!! The effectiveness of this product is DEFINITIVE! My water went from something like 4 inches of visibility to being able to read a newspaper on the bottom of the pond. I've been using it for about a year. In the summer, I dose about every four days and in the Winter, which isn't so bad here in SoCal, I use it every couple of weeks. This is an incredible product. It really does what it says. My pond is so clean, I can't believe what I lived with for years before this product. I enjoy my pond so much more now. Try it, you'll love it.

### ⭐⭐⭐⭐ This is good for maintenance...
*by O***S on May 14, 2025*

Good for maintenance but doesn't do much if you're having clarity problems already. A sludge destroyer is better to start with then add this for maintenance.
