As you may know, have a my 5 gal set up for my new HM Dmtri.
The only problem is, none of the heaters I'm buying seem to be working!
Well, the first one was a Hydor mini, which I didn't know only raised the room temp. a few degrees. It went up to 73 degrees and that's it.
I went and exchanged that for a 50 watt tetra heater that was pre-set to 78 degrees. Again, it wouldn't go highrer than 73 degrees.
Yesterday I went and exchanged it for a Hydor Theo, 25 watts. It's an adjustable heater that I put on 79 degrees. I think I plugged it in around 9:00 last night. This morning, nada. The water is 72 degrees.
I don't know, is there something wrong with what I'm doing? I can't imagine what it is. I guess I'll have to go return this one too.
