    Chlorine and Cya at night

    Is it more beneficial to add chlorine and cya later in the day when the sun is not strong?

    Add the CYA whenever you want. Adding the chlorine in the evening allows the full FC level to be in the pool overnight when the sun is not consuming it ... which is a slight advantage, but really does not make a lot of difference.

    Just to prove how little the pool store people know , one guy told me not to put cya in till after your chlorine because the cya will hold the chlorine at whatever level it is at the time. Oy !

    Wow. If only that were true! We could put chlorine and cya in once and it would magically hold forever! Talk about low maintenance. lol

    I was told by a pool store employee, when I mentioned I was looking for sideways return jets to improve circulation to the skimmer, that the problem could be simply solved by pointing the returns down, and to the left. The moon's tidal forces are far stronger than the wind which is blowing my debris past the skimmer and to the opposite end of the pool. It's the same reason toilet water flows counterclockwise. He also had a customer who couldn't get rid of his algae no matter what they did, until he directed his returns down, and to the left - at which point it promptly cleared over night...

    Have you ceased to be amazed yet?

    Wow. Just... wow. And tons of people trust these folks for advice and give them money. I wonder if that employee just makes up the wildest theories possible to see who will believe them.

    Re: Chlorine and Cya at night

    Guess that would depend on how you're looking at it--standing in the pool or above the return from the deck. left/right , it's all relative.

    Re: Chlorine and Cya at night

    When I was a kid I used to have a fish called an algae eater. He would stick his mouth to the side of the fish tank and eat any algae on it. Would love to tell someone in a pool store that if they went out and bought I dont know, say 23,000 of these things they would never have algae again!

    Thats All funny stuff. Jason should have a special topic for all the crazy pool store advice.

    No, it's really true. Another guy tried to sell me shock when I asked him where the stabilizer is. I just shook my head and walked away.

    No worries, the fish would die long before they had a chance to foul up the water! Then you just need to net out the 23,000 fish carcasses.
