Thanks for the reply. Yes, the chemistry is great have been testing all season with the 234s kit. I still have a few questions:

With regard to the floor cleaning system, do I disassemble the control valves (two little mushroomish things sticking out of the ground) and blow out from there?

I looked into the box with all of the stoppers for closing, for what are the wedge shaped stoppers used (looks like a wedge with the tip cut off)?

Also, I have a heater that I failed to mention, anything special about winterizing it?

Thanks again,
Kevin
