How to tell if heater is bad???
 

I have started to awaken to a cold dark tank. I dont know what is causing it.

When I check my heaters I find only half of the length of the heater is getting hot.

I changed two things before these overnite gfci trips occured.
1 - moved my two tunze 6055 on a 7096 to the gfci and off the reefkeeper
2 I added a older nano kora to the sump

Ideas?

I am traveling for the holiday weekend really worry about the dead tank upon return

Suggestions?

The heater is probably bad. They tend to go bad often.

What kind of reefkeeper is it?



Edit: I keep a kill-a-watt plugged into my heaters. If they start to burn out usually it doesn't happen at once. If they don't pull the rated watts within a few watts chances are they are on there way out.

reefkeeper 2, I used it as my temp controller.
Only problem is channel 4 is malfunctioning

why

Bad temp probe, or perhaps Electrical interference.

Skimmer pump was making my probe go crazy.

sorry let me clarify

the gfci tripped and the whole tank power was off, cold dark no flow

Turn channel 8 to always on.

There is a bug with the RK2 that they could not solve. For whatever reason if you leave channel 8 always on the bug goes away.

I have never seen it trip the gfci though. The heater might have knocked something out in the controller.

I have circuit #8 at the temp controller.

Number 4 circuit is stuck to on/off, I can choose auto but it doesnt give me the choices after.

ideas?

Sounds like it is burned up. I would contact digital aquatics and see if they have any answers.

My heaters seem okay, it is more likely the older kora.. It sounds rough in the sump.

I have reconnected the tunze 6055 to circuit 4.

So far so good.

I'd take the return pump off that gfci or get one just for that pump.

Thanks for the replies,

I have connected something to channel 4 and it is set to always on.
I have taken the koralia nano out of the sump.

any issues of a similar nature with the da reefkeeper lite?

How easy is the aquacontroller jr to program vs the reefkeeper II?

I have not heard of any issues like this with the RKL but regardless of the issue I still think the RK2 one of the better controllers.

I have had a couple opportunities to upgrade but after 3 years if dependable service i will stick with my RK2 until it dies. 7 channels is more then I need.

Thank you all for your help.

I have performed a reset and now channel 4 is giving me all the options of programming.

I have left channel 4 and channel 6 always on.
