    Going on vacation

    I will need to use pucks for a week while we are gone. CYA is currently at 50. Any guess as to how many pucks I will need to keep my minimum of FC 4? I will also be trying to up my CYA to 60.

    No idea. You can use the bottom of PoolMath to tell you how much FC and CYA each trichlor tablet will add, but no way to tell you how fast they will dissolve.

    Dichlor will add 0.9ppm of CYA for every 1ppm of FC.

    Trichlor will add 0.6ppm of CYA for every 1ppm of FC.

    Working backwards (for a 14.3k gal pool), 38oz of Dichlor (or 35oz of Trichlor) will increase the CYA by 10. The 3-in Trichlor pucks we sell (99% Trichloro-S-Trianzinetrione) weigh 8oz each. So in your case, you would want to make sure not to use more than 3-4 of them to stay in the CYA-60 range.

    But like Jason said above…we don't know how quickly they will dissolve.

    I think that 3-4 will last all week. And I can pull the remainder when I get home. Thanks
