Thank you Marie for your input. Just to make sure I am clear on your instructions...

So with 0.2 copper level you think it is OK to go ahead with the conversion process w/o a metal sequester? When you say I would be OK to go ahead and raise chlorine level are you saying all the way to 10ppm since at this point I don't have any CYA? And you mentioned to raise it slowly...so how long should I wait between adding each gallon to raise it in 2ppm increments? I don't think we have algae right now but last night the water was clear and I could see the bottom. This morning it is still a clear color but cloudy...I can't see the bottom in the deep end.

I will add a puck to the skimmer (sand filter) to increase CYA. Should I just use the pucks to increase the CYA or try to go buy a product to increase it?

Lastly, once I get to 10ppm I should keep it there until it holds from pm to am? At that point I would be through the conversion process and could let it drop to whatever ppm indicated by the CYA level?

Sorry for all the questions, I'm just tired of relying on the pool supplier for what has been questionable advice to this point and really want to be able to understand and do this on my own.

Thanks again!
Andrea
