Big mistake in trying to raise pH... please help!

I already said that you had copper in your water.
Question is, where did it come from? Have you been using algaecide?

Is your fill source from the municipal water supply, or is it from a well?

Thanks Janet I'll check that out. My water comes from a municipal source. From what I understand now, as this kind of water evaporates, the metals are left behind. That probably explains why the water has always had a strange metallic taste since we inherited this pool. I hope I haven't endangered my family by not taking action to correct it. Having never had a pool before, I thought it was normal.

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

Soda Ash=pH Up!=Washing Soda (Arm&Hammer)

This raises T/A as well as pH. T/A of 90 is nothing to worry about.
