PoolRx+ Mineral Algaecide Unit, up to 6-Month Algae Control, for 100-400 gallons, Yellow & White, New Formula with Silver.

We switched from bromine to Chlorine after using one in our pool was such a impressive change. My skin feels so much better than when i got in the spa with bromine it really helps keep our spa cleaner, and the water FEELS cleaner

This algaecide worked but it’s not immediate. After 5 days it was better and after 2 weeks we had our beautiful pool back. We did have to bring water samples into the pool store for testing every 3 days and had to add other products as well

This stuff works great in our pool. No algae all summer

Worked very well and I'd definitely use it in the future.

This is a great product for keeping the hot tub clean, clear, and non gritty.

Love this! We use this in our oil and cold plunge. Have been for a few years now. It actually works really well, and there is an option to use less chemical chemicals in your water.

Very good product. Used in our hot tub we were out of town for a couple weeks came back and algae 🙄. Except for chlorine the chemicals read good changed chlorine cartridge and didn't fix the problem so after a couple of days and ready to change the water. I ordered this yes the water turned a little blue at first but better than the green it was prior. But then after a day or so the water cleared. Will definitely buy again and definitely use before we leave on vacation again.

We keep these on hand for our hot tub. Has kept that stagnant water odor and slimy feel away for sure. We will always use this product for our hot tub. Easy to use and doesn’t bother my sensitive skin.
