1.55 lbs. Pool and Spa Chemical Chlorine Reducer, Water Clarifier, Algaecide and PH Stabilizer

I don't have my portable Hot Tub up yet here in North Florida Ambient Temperature is still to chilly to keep the hot tub tem high. So, I used what I thought equivalent measures of same tap water to "Cystalline Pool System Chlorine Reducer". It may not have been right. The testing strip on the Right was tested with treated water. the one on Left is plain tap water. There's some difference but not much. The Chlorine is greatly reduced as is the Bromine. I will come back when I have the Hot Tub up to give y'll a more accurate reading. I think it will do the job.

I have a 15' wide and 48" deep easy set vinyl pool. I was using a different mineralization product that would automatically dissolve into the pool and then flip over. I could never tell if it was working. I decided to try this product and see how it compared. It is expensive, but it goes a long way, and WORKS. If you have a small pool like me you'll barely make a dent in the can during your entire pool season. I only have to add the smallest amount of 5cc. The product is from Quebec so it's in metric units. My pool has less than 5000 gallons so I called to ask for help calculating. They where very friendly and helpful. Since I have about 4000 gallons give or take, I just add a little less than 5cc. By the next day I can see the difference. The pool becomes crystal clear. It makes being in it feel so refreshing. It even helps to clear it faster after an algae bloom. First I shock, then after the green turn to cloudy I add Crystalline and I feel it helps speed up the process. It also has reduced the amount of chlorine I need to add to the pool. I will say that easy set pools are really hard to keep clean and to keep the levels stable. When all the levels are right Crystalline does it's job best and makes the pool so beautiful and clear. It's expensive, but totally worth it

Did not receive the results we were expecting.

GREAT product to balance your water makes it much easier to maintain your pool.

Been using Crystaline in our pool for about a year. Honestly the pool has never been as clear and it takes all the chemical work away. Add it to skimmer, keep chlorine added and pool is crystal clear! Oh and the pool doesn’t need as much chlorine either. Works Great!

This lists chlorine reduction as one of its features though I noticed no difference in chlorine levels after using it as instructed. It did however help stabilize my ph and alkaline levels and that's important in a hot tub. The powder dissolved well and the changes in water chemistry were relatively quick. The packaging label was a bit lacking in specific instructions but all in all, it works.

I have been using this product in our small poo,l less than 5,000 gallons, and the pool water has remained crystal clear and I have found that I use less chlorine and the water stays very stable on the algaecide and PH stabilizer readings. I could see that with a larger pool that is product could save you money on chemicals during the pool season. I am pleased with the results of this product in our pool.

This is the first summer we have had a swimming pool and I am enjoying it more than I anticipated. Along with the pool came a starter kit of chemicals that included chlorine tablets, shock treatment, clarifyer, calcium and PH leveler. Fairly confusing, but I was able after a couple of weeks to get all the levels within acceptable range. Now I am using this product which replaces all of the chemicals except the shock, which I will continue to use once a week. The cost seems high but compared to the other chemicals I have used it is right in line. My levels are good and I'll continue to monitor any changes to the water and report back if this product does not perform to my satisfaction.
