HELLO,
New to forum and would appreciate any info. Will try to get to the point. I have a 10 year old above ground pool, vinyl lining 22,000gal. with sand filter. Relatively no problems over the years. End of last year had a late season algae bloom, thought I got it taken care of. Closed pool as usual, opened 3 weeks ago, water was clear with usual few leaves. Balanced water, vacuumed slightly cloudy. Added clarifier and water was good and has continued to be clear the entire time. BUT, cc would register 0. Finally dawned on me something was eating it. Sooooooo, started SLAM on Saturday. Readings as follows:
CYA 40
PH 7.5
TA 100
CH 260
This is what I have been doing and I guess I just thought it would have passed OCLT by now since water has been clear ENTIRE time.
Target shock level 16. Started Saturday noonish. Vacuumed, brushed, brought to slam level. checked every 30mins and readjusted to slam level. Hit 16 at dark that evening. Next morning large loss so repeated this process Sunday. Monday, Tuesday, and today checked 3times day and readjusted slam level to 16.
I have scrubbed all surfaces, skimmer, outlet and ladder. Is this an expected time frame if water was clear to begin with????? I have used about 25gallons of bleach so far. Should I just keep at it or am I missing something? Leaving on vacation in a week or so and don't want to back slide on progress.
Thanks in advance.
