### ⭐⭐⭐⭐⭐ Seems to work!
*by E***M on September 15, 2021*

When I replaced a smaller pool with my current 4x16' above-ground frame pool, I researched pool maintenance and came across a convincing site that said all one needs is liquid chlorine bleach, conditioner, and test kits for both. I already had a Pentair chlorine/bromide and pH test kit, so although it's super basic (don't know the free vs. whatever the other kind of chlorine is), I stuck with it so as not to spend a lot of money on a better one. When I used up the little bottle in the kit I had, I bought this one. It's too big to fit in the box, but it'll last longer. The "system" is working so well that I thought this product was broken because it always showed the chlorine in the good range, but I tested it on plain water and it showed no chlorine, so I think all is well!
