Just like what I buy in my local store but at a much better price. Will buy again. Very satisfied. Forgot to look at the amount of calcium though but haven’t had any white residue around pool edge or floating in water.

This product quickly boosted the chlorine level in my pool, leaving the water crystal clear in just a few hours. The process was incredibly easy—just add the recommended amount, and the shock treatment works fast to eliminate algae, bacteria, and other contaminants.Within hours, I noticed a significant improvement in water clarity, and my pool looked fresh and inviting again. It’s ideal for maintaining a healthy pool environment and can be used regularly for preventive care.I also appreciate that this shock treatment is effective in both saltwater and chlorinated pools. For anyone looking to maintain sparkling clean water with minimal effort, I highly recommend HTH 52030. It’s a reliable product that delivers great results every time!

The product worked, however there were no instructions on the package on how much to use for smaller pools... The package indicated it would treat a 13,500 pool, which was WAY larger than my 700-gallon stock tank pool, thus the four-star rating. I had to do some calculations and started out with a tablespoon, which after 24 hours was not enough. I added more which was still not enough after 24 hours. I finally, ended up using 1/3 of the bag which did the trick. My stock tank pool's interior has pond shield on it and there doesn't appear to be any damage to it. I did have to run my Intex pump with filter for over 20 hours (changing the filter three times during this period) as even though the green was gone, the water was still very cloudy. The box contains six bags which should be enough to last me many years as we rarely get a lot of rain during the summer (like we just did which caused the pool to go green!)
