I have been looking over the site and have been learning a lot about stains on vinyl liners.
I just reopened my pool and the winter cover tore open and allowed a lot of Pine needle and pine pod/things accumulate on the bottom of the pool. vacuumed and cleared water. Water is now very clear and the liner is supposed to look like tan pebbles, is now tinted evenly green.
Leslie's said I had a metal problem and treated with metal gone and now tests show no metal, but still green tint.
Some details. 10,000 gallons. CYA: 100 (thinking that 3" tabs are not the way to go), CH is 720, TA is 150, FAC 2, TAC is 3. PH is 7.4
I have been told I need to drain and refill. REALLY don't like the idea of wasting 10,000 gallons of water if I have to.
I put a 3' Tab on the bottom of the pool for a half hour and it did not make a change in the stain. Put some Spa PH Down in a sock on the liner for 20 minutes and it also did not change the stain.
Hoping for some hints as to what steps I REALLY need to make.
Thanks in Advance for the help.
