Meantime, I've been muddling through with this for 3 days now.
CYA is high for sure but this kit makes it a little hard to tell exactly how high.
I think it's between 100 and 150 - but maybe it's even higher.
My question is this - can I mix clean water and pool water 1:1 and test that solution to get a more accurate CYA reading? (I realize I'll need to double the result. )
