How To Change Out Heater?

[BamboozleBean]

I am taking a heater from my 10 gallon and moving it to my 20 gallon as it’s rated up to 25 I just have it on it’s lowest setting. My 20 gallon is empty and I have a 10 gallon heater to replace the one in my 10 gallon.
How can I change them out without the temp dropping or rising too much?

Just change them out. Unless the ambient temp in the room is freezing, having the heater unplugged for a bit won’t hurt anything. Mine is in the power strip with my pumps and I shut it off 10 mins every day to feed, and about 30 mins or when doing WC and vacuuming the sand.

Water holds it's temperature for hours. There's nothing to think about.
1. unplug the heater
2. remove the heater
3. replace the heater
4. plug in the new heater.

When you want to remove a heater make sure you unplug it but leave it in the tank a few minutes so if it was on it can let the heat go into the water.
They get quite hot.
