Ok he is the story. I went out of town for 2 weeks and came back to dark spots on the bottom of my pool. Upon closer inspection it is algae that has taken hold in the pebble finish of my pool. I confirmed it is algae by placing a puck in the spot and it will turn it white in an hour or two. I know I need to shock but in 5 years if pool ownership have never had to do it. Here are my stats
My water is clear just have the algae spots I am to shock correct.
Best place to get bleach they don't sell liquid chlorine in my area.
How many gallons of bleach.
Thanks guys I had a little if this algae last year and did not take it serious because it was the end of the season. Now it's time for war.
Ps before I left my cya was low so I have some pucks going now so that is probably the only reason my fc is 3
