BioGuardScale Inhibitor, 1 Quart, Concentrated Formula, Prevents and Removes Scale Build-Up and Metal Stains, Protects Pool Equipments

I have a "salt" pool. That means I have a chlorine generator that uses a cell. The cell needs to be de-scaled manually two times a year, of more frequently. Using the Scale Inhibitor has greatly reduced the scale on the cell.

Works as described.

I have city water and we deal with calcium build up on everything! I came across this the end of last year and decided to wait until this year to try it. My pool chemicals are always balanced, this stuff is a miracle! I put it in my pool upon opening and I can visibly see the calcium starting to chip up. When I empty my pool vacuum I can even see large calcium chips. This stiff is a miracle worker! It does not happen over night but it is working and I will continue to use it.

Worked like a charm. Excellent brand.

Keep in mind that this will only help prevent scale from attaching to pool walls. It won't reduce the amount of scale in the water. Lesson learned.

perfect

I noticed my pool had calcium build up due to hard water and other factors. My pool water was cloudy and needed a boost. I used a whole bottle of this and let my pump run for a few hrs. By the next day I noticed my water super clear and also less stains on my tiles. Will be using every month or two going forward!

It did nothing to inhibit or reverse my scale buildup. I purchased two bottles.
