EDIT My test kit showed up & showed NO CYA??? so I took a sample to a different pool store & they verified the results no CYA Test results posted in new post below
I have been trying to clear my green pool for the last week, pump running 24/7 while I wait for my test kit, which I thought would come today but didn't so I took a sample to the pool store
my CYA was at 140
Thats right ONE FOUR TEE!!!!!
so I know why I have seen very little improvement, I haven't been able to keep the CL level high enough to shock my pool.
The last owner must have gone hog wild with the tri-chlor
To get to a CYA level of 50 I need to drain about 65% of the water, I am worried because the water table is very high in my yard, so I I do not think I can drain all 65% at once.
Where should I go from here? Partial drain-then fill-then test until I get the CYA to 50 then worry about trying to shock my pool?
All ideas appreciated
