CrystalClear ClarityMax - Pond, Stream & Waterfall Treatment - 2.5 lbs treats up to 20,000 gallons

This water clarifier does exactly what it says. It does a great job, stopping algae growth and adds beneficial bacteria to the pond. The only problem I have is that you have to pre-mix the powder in a bucket or else it sinks to the bottom and crystallizes. I use this about every other week unless there is an algae bloom. This water clarifier doesn’t harm fish or Ducks. I would recommend this product.

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.

Controls hair algae well, have used it in many ponds for years. Although not as good as Bio-Pure, it is cheaper and very practical for small ponds and little worry of overdosing.

I have used and continue to use other products to help clear my 1500 gal Koi pond. Make no mistake, hands down this product works the best. When the pond gets cloudy I throw in 3 scoops and the next day I can see the bottom.5/22/22-My pond got really dark and cloudy. Nothing I was doing was working to clear it up. I have 19 fish, Koi and Goldfish.What I did, I drained out about 2/3 of my 1500gal pond using a small pump and my 4gal Shop Vac. Took most of the day. Then I started refilling with my garden hose and even before the water got to the waterfall pump inlet level I dosed the pond with 4 scoops of ClarityMax. Got cloudy as hell even when the pond was full. Then I turned on the waterfall pump.The next morning I could count the pea gravel stones that were accidentally on the liner on the bottom. And NO fish died.This stuff works!!!!

Finally cleared up the pond water. The algae stains might not have gone away that well but the water itself is clear, in a way that powerful UV-C and filtration could not do.

My pond is clearer when i use this

I recently purchased the Clarity Max Plus for my ornamental pond. We had algea bloom and couldn't seem to get it under control. I bought it because of the recomendation of a co-worker. The product improved the problem but never actaully got rid of it as it said it would and I even doubled the dosage and prayed it didn't kill our fish but still the green water persisted. I hope it works better as a maintence product than an actual treatment, I have since drained my pond and cleaned it out and started over. I'm crossing my fingers.

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.
