Biocube 32 overheating….

[SaltlifeHokie]

Got my biocube setup and cycled and I have my brand new Ehiem Titanium heater set to 78 and the water temp is 82. Why the variance? My house stays around 70 degrees. I set the heater back to 76 hoping that would make a difference but it’s still 82ish. Do you think I got a bad heater?

If you unplug it does it stay at 82?

My 32 gal biocube with stock lights, an upgraded return pump and a hygger mini wave maker runs 79-80 with an ink bird running a fan at 80. House is at 72*. Summer with house at 75* the an runs a lot to stay under 80*. I have a heater but don't think it has ever turned on.

It’s 79 with the heater off since last night. Think that would be safe to add fish? Should I just roll with no heater and monitor it more closely?

The return pump may be oversized.

I was using a pond pump in a 20 gal to mix new water. The pump by itself raised the temp to 92 degrees.

How big is the return pump?

cycling of lights on a closed lid will raise the temp.

It’s the stock return pump that comes with the kit

I unplugged the heater last night around 8:00. 13 hours later it’s still pretty hot and the lights have been off.

With the lid and pump on those things it insulates pretty well with the heat that comes from the pump etc,

Also check your heater for calibration etc.
