Test Solution, Pentair OTO, 1 oz. Chlorine, Bromine

Excellent reagent. Works as advertised for chlorine/bromine detection. Good value for the money.

Excelente producto! Me abrió los ojos de la cantidad de cloro que consume mi familia y me llevó a tomar la mejor decisión.

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!

Used for pool.

Pentair OTO solution is excellent to test chlorine levels daily! Quality product and provides color intensity representing chlorine levels in spa.

Nice because it is a larger bottle

Use it to diagnose well water that should have cl2 feed... I add a couple of drops in a small white cup and look for yellow! Easy

As advertised, well packed, zip lock bag, shrink wrap at neck of bottle/cap, and 11/2024 expiration
