We are going on 3 weeks with green water! Cannot get the water to change at all.
We have an in ground, vinyl, 35x15, less than 20,000 gallons.
It is definitely high copper, chlorine was perfect, had the water tested and high copper metals.
All levels are in okay range, except copper @ 3, pH is a little on the low side.
So we bypassed/completely disconnected heater thinking copper corrosion was coming from heater.
Drained water 6-8 inches 3 different times and refilled, hoping to at least dilute the green....no change.
Lowered chlorine to .5 and then added 2 containers of Metal Free....no change.
We fear draining completely as we have had a lot of rain, ground is saturated, already have weak walls due to previous liner change.
What will work?
