Thank you for the reply.

My numbers as of a few moments ago are:

chlorine : 0.5ppm
ph: 7.6
alkalinity: 90
calcium: 250
cya: 50

I am a little concerned with the chlorine that low as with the water heated to 82, it is only a matter of time before algae forms... However, right now the water is crystal crystal clear...

What are your thoughts on oxalic acid instead of ascorbic? The reason I ask is that oxalic is half the cost of ascorbic around here. I think there is a dealer close by that has Pro Teams Metal Magic. I will pick some up and try that.

How do my water balance numbers look?

Thank you for your help.
