Periodic Products CuLator Ultra 4.0

If you see bad reviews for this product, either it’s not being used correctly, or the person is trying to fix a problem that this product is not capable of fixing.Before I started using this, I used to use the sequestering agents all the time, and then half way through the season when it got really hot and I had to use more chlorine every day, all the metals would start collecting all over the plaster (anywhere there is metal or re-barr under the surface). Then I’d have to use Muricatic acid to remove penny sized stains in about 10 different places in my pool.When I use this product at the start of the pool season, I don’t have to use any sequestering agents AT ALL. One of their Powerpack 4.0 units lasts me an entire season (May – September) for my 26,000 gallon cement/plastered pool. I get ZERO STAINS of any kind when I use this product.The ONLY chemicals I use in my pool are Sodium Hypochlorite (12.5%), PH-down, PH-up, and the powerpack 4.0. I need this product because we have a heater. If I don’t use this product, I get iron stains EVERYWHERE half way though the season.If they every decide to stop selling this product, I’m going to buy 20 of them and hope that they never go bad :)This product is NOT FOR REMOVING STAINS, it’s for preventing you from getting stains in the first place. If you have stains, use some dry acid in a sock or buy one of the muricatic acid PVC tools that goes on the end of a pole. Don’t use this product in conjunction with a liquid sequestering agent, use it instead of adding a liquid sequestering agent.
