5.5g Nano and heater issues

[andsoitgoes]

Gary - the strange thing is that's not the case at all - I had it down to 75 last night, by the time I checked my tank this morning, it was at 83.7 - Not makin' me happy! I have it positioned right under the outflow of my HOB filter, too.

*Dolphinpoint - does your house temp flucuate at all though? I know mine does from time to time, but maybe I need to look at getting a tronic. What model is yours?

I'm really not sure what to do, normally I'm not up late enough to see how much of a hit the temp is going to take.

I've got a Hydor/AllGlass mini 50w heater in there, I've had a lot of luck with the brand before, but I wonder what the heck is going on now. I don't want to fry my corals overnight, not sure what's better - freezing, or frying? UGH!

Thanks again all

Ok, this could be your problem right here. If the heater is right under the outflow it will be cooled off but the water flow. This will force it to work harder and heat the tank more.
Try moving it near the intake of the filter that way the warm water is drawn into the filter. This should bring the temp down.
Or if you have the room try the heater inside the filter. That is where I have all of mine.

that's what I was going to do once I upgraded the filter to an AC unit, more room and it'll fit nicely.

The funny thing is I did the same on my 44g and I still had the heater running when it was above the set temp - and prior to this, I had the heater far to the left, away from the outflow and near the intake of my powerhead...

Questions, questions!

Outflow or inflow makes no differance. The heater needs to be placed in an area where water will move across it to ensure uniform heating of the water.

Having the heater under the outflow isn't going to make it stay on any longer than if you place it beside the intake. Again, all that matters is that water flows past the heater.

If this doesn't work, it's quite likely you have a dud heater.
