Hi, We are considering converting to chlorine from baqua but I want to make sure the amount of chlorine it sounds like we will be putting into the pool will not harm the heater. We have AG pool. 17' x 24', my husband thinks its 13,800 gal., we have a sand filter, 1.5 hp pump and a stay-rite propane heater. When we got the heater we had the installer plumb it so we can bypass the heater. Would it be better to bypass the heater until most of the conversion is done then just add it back in so its not getting all that chlorine (is chlorine corrosive? I know I have have put holes in some laundry when I used too much bleach, lol) . I'm calling the pool store to see if we can return the baqua we have left otherwise my husband wants to wait until next year but due to an unfortunate accident we have lost half or more of our water so since we are adding so much water I think this would be a good time to make the switch. If we can return it I will be ordering the test kit and looking for bleach. Thanks for any advice.
