Worked as it should.
Worked as it should, had to use 2 bottles which I expected. Calcium was very high.

If you are on Nature 2
The system I use in my pool is not compatible with this product. I use the Nature 2 cartridge system with NST chlorine tablets. This results in high calcium hardness in the water. I tried this product. Unfortunately, it did nothing for the calcium hardness but it did raise my phosphate level so high (over 6000) that I had to do three treatments to reduce the level (the pool will not hold chlorine when phosphate levels are high.) Also, this company will not allow the return of chemicals.

Thought I would see a greater reduction when using the prescribed amount.
