No chlorine but looks artificially blue.

Day one of startup, pool water was turquoise and looked true. Week two my wife says the pool startup guy added what looked like dishwashing liquid to the water. When I brushed the pool the next day I noticed the water was blue, but the chemistry had not changed. Today I am home and saw pool guy add this blue stuff into the pool. There is no chlorine in the water. Any ideas on this blue magic?

day 1

After pool guy added blue substance the first time.

Today

Huh. No clue? The bottle isn't even labeled it appears (bad chemistry practice that!), Do they leave a bill with anything listed on it?

Pools are often slightly green tinted when first filled, then turn to their intended (hoped for!) color in days. What color is it that you intended and what color is your plaster?

Why isn't there chlorine in the water????

This is just a guess, but I would guess clarifier. My brother in-law has his concrete pool taken care of by a local pool company and they add clarifier from a squeeze bottle like that. Apparently they purchase in bulk and dispense as needed and it is blue and does look like dish washing liquid. Next time they are out there go ask what it is.

Assuming you're correct, clarifiers will gum up those cartridge filters over time. I guess then the pool service tells the owner he needs to buy new filters then?

No bill as this is part of PB startup.

Plaster color should be more turquoise than blue.

FC measurements have been 0-1. The salt water system isn't active yet as the pool is new. We aren't swimming yet.

I found some of this clarifier on Amazon. Looks like the same stuff. Thank you.

Robot MX6 added to pool yesterday. 20 bags of salt are on hand and I will purchase liquid chlorine, baking soda and muriatic acid. The real fun starts next week when I start adding salt, activate chlorinator and test all parameters.
