Jagers are real nice.
That is almost all we run.
-Possibly due to the sale we found last year.
The yearly seasonal sales have good price drops to catch if you know where to shop.
We may have been in the beer and reef tank forums a bit too much.
We're gadget geeks.
A heater is known to mess up the guys with their beer batches and reef coral guys.
The heaters get wonky and temps sail their projects into the heated unknown.
The freshwater heat issue is not so bad I'd think, but we like gadgets and accuracy.
Correct me if I'm wrong.
I'd say some plants surely will melt or do something negative depending on the species.
The gadgety Inkbird ITC 306T is heater controller that lets the user digitally control the Jager heater or combo of two (2) heaters.
It does not have to be a Jager, but they sure work well.
I'm still using some old Ebo-Jagers from 2003 too.
Our Jager heater gets dialed to about 86F to make sure it is working on the way up in temps.
As long as it is pugged in, the controller now controls the Jager heater and tells it what to do digitally and is had for about $34 online.
It is very easy to use.
It can pick up on the temp dropping 1.0F and send the Jager heaters into action.
** use two heaters for redundancy.
Our situation-
The one tank in the room a few moments ago was reading 82.0F
The tank water temp on this white certified stick tester stated 81.7F.
The certified stick tester stated the room air was 81.9F.
All in all "one does not need these", but if inspector gadget had a freshwater planted tank, he may just go-go gadget Inbird 308T.>
