Ha ha … those same thermometers. My trigger fish constantly picks at it like he’s trying to eat it , or playing .Thank you everyone for your input and suggestions. I have ordered the Inkbird and two finnex heaters and changed up one of my returns - which I think actually made a difference today because the temp rose a lot faster, but its warm out today so I'l have to keep an eye on that.
On a [sort of] related note - has anyone ever experienced your glass thermometers breaking? I have had two - one in the Sump and one in the DT and they both broke. Just broke, wasn't hit with anything, no reason, Just look one day and its broken. It's like the bottom just explodes. Now I have those little metal balls in my DT and trying to get them all out.
Just thought I would ask. Have googled it and seems like i'm the only one. LOL
I moved it to the sump and have had the same one for many years
There is so much coralline algae on it you can barely read the numbers until cleaning day
