Hi, I have been looking all over for a cheap thermometer just to give me a ballpark range of where my water temp is. I don't care about being exact and precise, but I need to know when I can buy my tilapia for algae control and I want to know how far off I am from 60 degrees!
I bought one from Amazon (link below) and it was complete garbage. The first one I got was actually missing the glass part in the middle where the mercury is. All I got was the plastic frame! When I complained and they sent me a new one, that thermometer is telling me I have 72 degree water today (it's MUCH colder than that, I can barely go in up to my knees).
I need one that is cheap and submersible. It seems like everything I try to find is for a pool and it floats. Surface temperature does nothing for me!
Here's a link to the one I tried twice now:
