HTH 52037R Pool Care Shock Advanced, Swimming Pool Chemical - Cal Hypo Formula, Prevents Bacteria & Algae, Restores Crystal Clear Water - Shock Treatment, 1lb (12 Pack)

Ok, here we go... So I live in Florida, so everyone here knows how hard it is to keep your pool from turning green... This product works great. I use a bag a week, with my normal chlorine and no green.... I liked it enough to buy it again. Great people, and a great price... Happy camper here.

This shock works great for me. I like that it does not have stabilizer in it, so I do not have to worry about chlorine lock. I add a back to my above ground pool every weekend to boost the chlorine from my salt chlorination and it keeps the water nice and fresh. I like the 6 pack so I have some on deck when I clean the pool.

Best shock we have used - pool has never looked better! We have tried many brands from pool speciality store and home improvement stores. This has the best results we have seen in 20yrs

Use it every year

HTH always has and always will be my go to for pool products

This product works better than Clorox for me. It may be due to its larger particle size. It clenaed my pool when the Clorox failed

It works..can't beat the price either

Works well. Use every week as per directions
