Im not sure why we all figure we need titanium heaters???....especially when most of them are proving to be crappy.....most of us have sumps and the likelihood of a heater getting smacked around and breaking is low.....to me nothing beats and old fashioned ehiem/ebo-jeager glass heater.....in 20+ years of fish keeping Ive never had one fail.....( I do have a titanium heater too....a jali run by my ACjr....three years and so far so good)

Same... enough already!

Running an aqua controller I checked the log and it looks like maybe an amp jump at a point but nothing else really stands out?

This morning corals are bleached, hammer is looking near the end only missing one fish now figure he is buried in the sand, toad stool is limp

Trying to get the tank temp up two 300watt heaters going right now

Hey, sorry to hear about your situation,..... can totally relate. To make a long story short, I had to replace my first Aqua Heat Titanium heater within 6 months (Kevin replaced it, no questions asked). Thinking that the titanium heater was still the way to go (and with a larger tank upgrade in the process), I elected to buy another one to supplement the system. Well, needless to say, one stopped supplying heat even though there was power to the heater and secondly,...... but more seriously,.... the second heater shorted out and melted part of the controller. That was enough for the Aqua Heat and back to the good ole Eheim Jagers, for me!

Do you have a ground probe in the system? I'm assuming that you do not, which would explain why the GFI didn't trip...

Eheim Jagers FTW :mrgreen:

Update.

The good
- Only lost one fish the golby the rest came out of hiding and are eating again
- removed the other heater and replaced both tank back up to temp
- Hammer and some zoe's are coming back slowly

The Bad
- Aiptasia outbreak going on
- Tank is green very green major algae outbreak I suspect this is due to tap water and prime for water changes as I could not get enough ro/di at the time
- Snail are dead and they smell really bad
- Toadstool is limper then me after my snip snip today

I have 4 300W titaniums sitting in a box that either shocked me... coocked the tank or just quit heating all together... and they were in fresh water LOL...
Just got 2 new jaggers and am happy as a clam again:)

A GFCI will not trip if both the Hot and Neutral wires are exposed to the water at the same time ie; the seal on the heater let go and flooded the tube.
If you have a GFCI and a proper ground probe, the GFCI will trip.

FYI, without the ground probe, and both wires being exposed to water, you could have gotten a serious or even deadly shock if you touched the water.

Same can go for those of you out there with ground probes and no GFCI.
An exposed wire in the tank can flow back through the probe, possibly without issue, but you put your hands in there and tada, Christmas Tree. Especially if it's the Hot that's exposed.

Final thought;
Don't put all your equipment on one GFCI, unless you don't mind everything being tripped at the same time

My pumps have blown GFCIs for no reason.... cant use them on my returns or wont being the case now that its happened a few times...
I was told its the static or magnetic current they create that can trip them even though they are just doing thier job....
I use a probe on everything and its saved my life more than once...
If i were safe i would kill power before putting my hands in there...
