It is especially effective at controlling salt water generator (SWG) electrode scale formation without contributing orthophosphates to the water which inhibit chlorine sanitation and act as nutrients for algae growth. Features calcium and metal stain reducer. Contains no phosphorus which contributes to algae growth. Calcium scale prevents and removes calcium scale from pool surfaces. Metal stains prevents metals from staining pool surfaces. Salt chlorine generators prevents scaling which extends cell life. Patented formula non toxic, nonhazardous, economical.

After following the instructions closely, I added it to the pool, and have been adding weekly as suggested. It appeared to work well the first week, then things went back to as they were. We get flakes of calcium from the salt water generator, and I was using this to eliminate that, but the flakes are back. We were hopeful that it would work as advertised, but now are looking for another fix.

Have noticed calcium scale being eliminated more with each use. First started using this summer, and am extremely pleased......just be aware with purge dose chlorine will be depleted for several days afterward so follow directions and plan appropriately in advance.

I brought my pool level up above its normal level and added this product in hopes of removing the white scale ring around the pool. This appeared to be working but after two weeks, it is still the same as before. This product does take the chlorine out of your pool as stated on the bottle. So my white ring around the pool was still there, and I had to add shock back to the pool twice to bring back the chlorine levels. It didn't seem to work for my white calcium ring. We have a heavy amount of calcium in our water supply though so maybe it will work better for others.

Works great! Breaks down calcium deposits makings pool walls and floor smoother. Best product I have found. But kinda pricey. And absolutely kills your chlorine and expect a struggle to get the levels back up again.

Excellent product to help manage scale build up caused by by pool salt chlorinator. I read about this product from the manufacturer and wanted to try it. I experienced a build-up of scale in my spa only which is attached to the pool. Add 3 ounces per week into my 12,000 gallon pool skimmer and it helps tremendously. Worth the money and would buy again.

I have been using this for over a year now and am extremely satisfied with it. There are however some things that everyone should know when "trying" or using this product. First, it IS NOT a miracle cure to not have to scrub the pool tile on a weekly basis. I did have some scale on my tiles from a pool service that was not properly scrubbing them. After starting to use this product, over TIME (weeks), the scale was removed with weekly brushing and proper chem management. Basically, if the water is not balanced and the tiles are not scrubbed weekly, water line scale is still possible. I imagine that to be true of any similar product. (Orenda has an App for water balance and chem usage. I HIGHLY recommend using it to sort out your PH, ALK, Calcium, Stabilizer, etc.).The second thing.... Initial startup. The initial startup of using this product requires a much larger dose than the weekly maintenance. When the startup dose is applied, the chlorine level WILL drop to nothing. This will last for several days or so. I do not know why, but chlorine will try to react against this and.... the chlorine will lose that battle:-) Orenda has information on their site about this. But, in short, this is temporary and this chlorine reduction DOES NOT occur with weekly doses. I guess the chlorine soldiers figure out that this is not an invading force and go back to normal. Haha. That is my scientific explanation.Long term how does it do? I have a 3 year old pool and have no staining on any of the metal hardware in the pool and no water line scaling at all. Also, I originally purchased a couple quarts and went to the gallon and just refill the old quart bottles. It has been cheaper for me to buy by the gallon.

Used to eliminate carbonate crystals caused by a water imbalance. Not all crystals can be removed. I happened to be unlucky and did not receive total results. However, product did help. Why did I give it 5 stars when it didn’t totally solve my problem? The company is fantastic. They have so much information on the internet to educate consumers. Their customer support is fantastic. They believe in their product and it shows. I will have our,pool “polished” to remove my remaining crystals and will move forward with using Orenda products. I believe their products are high quality.
