Welcome to our forum.
Pool/spa thermometers are not reliable. If you really want to check temp use a digital thermometer.
Just curious if anyone else has taken their tubs temp? I threw a pool/spa thermometer in my HS at 104 and it reads about 110! I think it is probably the thermometer itself but phew that is hot!
I fed the neighbors cats a few weeks back while they were on vacation. They have an old Morgan spa with non-digital controls. Was gonna try it out, so I bought some dichlor shock and dosed it real good. The temp was low, so I cranked it up. Just has a dial that shows cool/warm/hot. Came back the next day, opened it up and the floating thermometer showed 114 F. I believe it. Could not get into the spa. I turned it back down and never opened it up again.txwillie
