Two consecutive posts. While I'm at it...RE: CYA.

Looks like if I want to raise my CYA level 5 ppm. It will take about 1 lb disolved in the pool.

18x36 9' deep end 3.5 ish shallow end rectangle.

When I did my CYA test it was full a little past the 30 marker and I think I could faintly see the dot at the bottom.

Everyone concur with adding the 1 lb of CYA. I'm skitish since I was way off the charts all of last year.
