Is it cloudy? Is it green? Worried about things growing...unseen?
Paying a service for your pool, but you feel like a fool?
The best test for me, is Leslie's (its free!)
They'll go through the motions to sell you their potions,
But you'll at least be the wiser, and if you're a miser,
You can get the same stuff cheaper at any big box or grocery store, or you can confront that questionable pool company with their printout showing exactly what they've put in the water that you let your kids, play, splash, and ultimately drink too much of as they play marco...pollo...FISH OUTA WATER!
Whew...
Bottom line...
Leslie's will test for free and tell you what to get, just go elsewhere to get it cheaper.
