Famous last words!
I used to put them in the tub... But then switched back to on the tape. For a few reasons
1. Do u put the probe on the substrate or under it?
2. What if the snake moves it from ur location and it fails.
3. Mine r water spillers so what if the probe shorts out.
4. How do u attach it securly.. Tape naw not good... Glue.. PIA..
5. What about tub cleaning. Now i have a probe attached to the tub.
6. What if i need to have that tub open?? Will be cooling and the herpstat will be trying to compensate and. Heating up the other tubs.
Basically ive determined through trial and error that my tubs sap ~ 16 degrees.. My flexwatt is at 106ish and my tubs are 91 ish.
Its just substantially easier imo to have it on the tape.. (mines cut into the shelf below the tape) but frankly its whatever works.
My best friend in the bp world has his in a dead tub.. And it works for him and hes a much larger scale then me...
