    New fill, test for CYA?

    This is a great site! I have been to pool school and have used BBB for a couple of months now. I just drained and refilled my pool due to high CYA. Is it necessary to test the CYA level in the new fill water before adding more? I didn't think so, but want to be sure.

    Fill water will have no CYA.

    Welcome to TFP cbaker!

    No CYA in the fill water, so you will have to add it. Check out Pool School and start with the ABC's of Pool Chemistry. Enjoy the forum and ask questions as you have them. We are happy to help.
