Ahhh so we need to tell you how to add CYA.........we say put it in a sock (yeah like you wear) or stockings. Either hang it off a broom handle right in front of the return or put it in the skimmer (leaving the pump running until it is all dissolved) make sure to not block the water flow.
Our house was a foreclosure but I did not get to demo anything

Did do a L.O.T. of cleaning though!! Oh and painting and fixing and/or finishing things done before we got it. It was all stuff we could do on our own so we SCORED big time on it!!
Just think how smart it was to start on the pool. Once you get it done you can jump into it when you get hot from working on the other projects!!! I love to jump into the pool while mowing the 6.5 acres when I get hot! Cool off then jump back on in my soaking wet clothes LOL
