    Phosphates?

    I went to the pool store to get my water tested and he said that it is high in phosphates. I have owned a pool for 20 years and never heard of this. He said it is from the rain water. He said it is at 300. He said that I needed to add a bottle of Phos Free. I usually use Pool Doctor but went to Leslie's because I needed chlorine and they are closer.

    Re: Phosphates?

    You dont need to wory about phosphates at all. They are irrelevant in a properly chlorinated pool.
    How do you chlorinate? Do you have your own test kit? Did Leslies test the water? What were the results?

    Ignore them.

    Phosphates are food for algae. Wood is food for a fire. If you don't have a fire, it just sits there, same as your phosphates in the absence of algae.

    Troublefree does not mean Maintenancefree. It's like brushing your teeth: You can spend a couple minutes a day and pennies a week or go to the dentist once a year and spend several thousand dollars.

    Re: Phosphates?

    I meant how do you add your chlorine? Liquid, powder, or pucks?

    Sorry, I thought I said that. I use liquid chlorine. Only use pucks when I go on vacation.

    Excellent analogy.

    Re: Phosphates?

    I just had my water tested at my local pool supply store and they said my phosphates are at 2500 ppb. They recommend--for about $75--the commercial grade of Phosfree. The phosphate level was 100 ppb about 5 weeks ago and the jump is due to the enormous pollen drop we get in Houston this time of year. Pretty much everything outdoors is covered in a yellow dust. Every few days there is a yellow line on the tile in my pool. It's finally starting to subside.

    My numbers are as follows:

    FC 7.0 (just started my SWG so it's a little higher than normal)
    CC 0.0
    pH 7.5
    TA 80
    CYA 80
    Hardness 355
    Salt 3500

    I take it that even at 2,500 ppb, I should not worry about phosphates. Correct?

    You are correct
