I have a Raypack 140K BTU heater professionally installed. Check valve installed after the heater, with in an inline Chlorinator. PVC piping from the filter to the return pool return line. I have read and re-read the manual but, I am wondering what chemicals should I use and what chemicals I should not use. What should I check for as for as chemicals. It's brand new three months old no problems. I just want to make sure that I keep the corrison levels down. What would you recommend?
Also, I live in Chicago, would you recommend winterzing it and leaving it outside or bringing it back inside for winter? Any and all suggestions will help.
Thanks again all.
