Storing Test kits ? Inside or outside?

[cwstnsko]

I try not to keep any pool related chemicals out in the heat and sun. I keep my test kit, acid and chlorine in the house.

My pool company even mentioned the possibility of keeping the test kit in the fridge .

Hobby used to involve a color darkroom BD (Before Digital) and used to keep bulk chemicals, film and paper in the fridge. After a couple years I never saw any degradation and color developing and printing is very sensitive to chemical changes. I keep the pool water test kits inside, out of the heat, and have a bunch of bulk refills that I keep in the fridge. I only open those containers to refill the ones in the kit.
