Not literally expecting the heater to respond, I am not that crazy, yet. lol
Dont even know if I am actually asking for help as much as I am venting in this post.
I have a tetra 100 watt heater on my 29 gallon that is not fully submersible and that has a little red dial on top to alternate heater power on a scale between + and -.
During the colder winter days, the setting I had it on kept it right at like 79 degrees. Well, now it is warming up a bit, and our AC is on, forgot to adjust the heater (totally my fault, I know

), and the temp dropped to like 68 degrees. I adjusted the heater a tad bit higher, woke up to my tank at 82 degrees!!! So I adjusted it down just a smidge, and currently getting temp readings of 78, which I am pleased with. And the dial is only at like 10% closer to the - than the + on a scale up to 100%...did that make any sense??!! LOL
I am just frustrated with this stupid heater and its extreme sensitivity!!! Thankfully there was no damage done by the fluctuating temps (at least that I have seen), and I check my temps on both my tanks multiple times a day as I am always afraid of a malfunctioning heater!
Anyone have this heater? (It came with the top fin 29 gal set up from petsmart last year) Anyone else want to beat the heater up too?
