How to I do this safely

[Yates273]

I have been wondering for a couple weeks why my Zoas have been closed. I have an Inkbird set up on my tank and it has been displaying 79-81 degrees so it never crossed my mine about water temp. I just checked temp with another thermometer today because I noticed my heater was off and it reads 64 degrees. Apparently my heater took a shi! and was stuck on but the Inkbird shut it down. I plug heater into another outlet and no matter what I do it’s stuck on. So I guess the Inkbird did it’s job by cutting heater off not sure why the temp reads 81 but anyway. What is the safest way to get the temp back up without hurting anything. Several soft corals acans zoas and a few fish wrasse two clowns and a Randall’s goby. Also 2 shrimp.

Slowly. Plug in a new heater and let it rise slowly on its own.

Is it ok if I start off with a 50 watt to about 75 for the night Then take that out and install my new 100 watt set at 78. Or should I just install the 100 watt set at 78? It’s an eheim Jager

Your first way would be more gradual. Or you could just use the EJ but set it to a lower temperature at first and then adjust it up slightly at intervals.
