No algaecide. The only tri-chlor I’ve used was in the two bags of powdered shock (40%), but that was six days ago when I was dealing with algae.

Actually, you said “it could be” copper so I wanted to get a second opinion. Sorry if it looked like I didn’t read your post. They basically backed up what you said but because I didn’t have a large enough sample, they couldn’t determine exactly what metals are present. I’ll find out later this morning.

Let’s assume I have an abundance of copper in the water. With the pool’s current state (FC 5+, pH 7.0, TA 90), can I treat the pool with a metal sequesterant, or do I have to get the pool chemistry in order? Also, any chance the oxidized metals are keeping my pH from rising past 7.0 despite 14 lbs. of soda ash?

Thanks
