Hoping you guys can answer a question. We have a 27' round ABG that was installed last summer. We opened it about a week ago. Put the salt in and got the level up to 3200. In the meantime, we bought a clear solar cover that has been on the pool the last two days. Yesterday pool turned green. Went to pool store and they told me to shock it. Put in the shock and later added algacide per their instructions. Still green this morning but water is clear.
My questions are: My salt level dropped down to 21000 overnight after shocking it. Is this normal?
Should also mention that I only have test strips to use for now. Shows the chlorine level is still high so I don't think it burned off overnight.
Also...my pressure gauge on my filter got damaged....pool people are supposed to be bringing me a new one this week. So I can't even tell when to backwash the filter. Filter has been running 24/7 so we could get the salt levels up.
I'm taking a sample to the pool store today and will order a decent test kit. But in the meantime, is that normal for the salt level to drop so much overnight after shocking?
