I have my K1515 kit coming tomorrow to add to my K 2005.

But meanwhile, I did do the "shot glass method", and I am above 20 ppm for cl. And my pool is getting better. Will add more bleach tonight and then test, then test in the morning to see if I lost any.

I also, brushed the sides really well this morning.

I feel like there is a sparkling pool at the end of this tunnel.

Thank you all for your help!
