I've been doing some quick research and have yet to come upon a definitive answer, at least as far as I can find right now.
I've had a CH reading of 90 for the last couple of weeks and am concerned about whether or not I need to bring it up to the 200-300 range short term. I dd notice what appeared to be some metal stains on the fiberglass steps, on the vertical surface - go figure. I did read a report or two of possible metal staining.
Does anyone here have an opin on this ? Specs in signature.
Thanks in advance./Dave
