Just opened my pool. It's clear but I noticed I'm all out of my testing 870 powder to do an overnight test so I'm using the old stuff from last year that has turned black and gritty. Not very reliable. Ordered new stuff and it's on it's way but at this time my plan is to just continue dumping bleach in as my old stuff is showing CCs.
Question 1: Is that the best plan of action at this time until I can get accurate readings? Like I said I'm not even sure my CC reading is accurate but I'm assuming there are CCs since it turned pink quickly.
The other thing is when I use the standard pH and chlorine test kit (Taylor) my chlorine test is showing a dark dark yellow brownish color, way off the chart. Normally when we open the pool our tests show 0 chlorine.
Question 2: What could this mean? Could my chlorine test kit also be bad from last year? We did have it in the garage all winter so maybe that's why.
My CYA is also 0, which has happened before.
Question 3: Can I add CYa stabilizer while SLAMMiNG?
I have a lot of dirt at the bottom but also a lot of bleach currently in the pool...
Question 4: Should I pick up the dirt using the manual vacuum via the filter or should I risk the large amount of bleach won't affect our electric Dolphin (they say not to use the dolphin over a certain amount of chlorine and I'm certain we're currently over that level.)
