Hello! Just opened our pool yesterday. There was a lot of black silt streaked in the bottom. when we tried to vacuum it up, it came up pretty easily but... there is like a residue that isnt coming up under it. Hard to explain but it left the white bottom of our liner looking stained. If we scrubbed it, it came off but it is difficult. First, anyone know what it might be? We have had the pool 8 years and never had this issue. Second, my numbers last evening before any adds were:
Temp in pool 58
Temp out of pool 62
Added 1 gal 12% distributed around outside of pool and 1 Trichlor Puck to skimmer (didnt have enough 12% and CYA on hand-my bad-and it was getting too dark to stand waiting for it to dissolve). Pump running 24/7. Vacuumed last night manually. Turned on 'lil Shark vacuum this morning to auto run. Have not put stairs in yet.
This morning my numbers were:
pH 7.8-ish (leaning higher?)
DNT TA or CH again
Temp in 55
Temp out 53
First... Is there anything I should do with the liner? I would assume if my cc's are 0 i do not have algae or am I wrong in that assumption? How should I handle the mess on the bottom & bottom edges of the pool?
What should my adds be at this point aside from the CYA?
Should I continue to keep at shock level?
Thank you for ANY help you can give me. I think in the past I have erred on the side of caution and over chlorinated. I would like to get away from that.
This site and you all are fabulous!!
