Copper in my pool

[RJDriver75]

We just bought a house with a pool and the previous owners used an ionizer. With the high winds we have had here lately the winter cover blew off, so I figured what the heck and took a sample of water to play with. They left a couple basic drop tests (chlorine, ph and copper) behind so I tested the ph and copper. The copper test showed .7ppm. From reading other posts, that sounds quite high. Should I be concerned and if so what can I do? Just to be clear I do plan on ordering the TF100 test kit when it gets closer to opening time. Thanks!

Copper at 0.3 or higher has the potential for staining, and it is best to replace water to get the copper level down below that. I don't know which copper test you have, but some of them are not very precise. So things could be worse, or not as bad, as they appear.

Until you get the copper level down, it is important to keep the PH below 7.4.

Thanks for the reply. I was afraid of that. I have the Lamotte Model EC-70 Copper test kit.

That is one of the better copper test kits. It is still +- almost 0.2 at the high end of it's range however.
