Yes Titanium heaters fail though I didn't know mine was going to blow up or become separated exposing the wiring. I was lucky I didn't fry.
Here is what happened....
Oct 2nd, I started my cycle in my tank. 2 heaters were running. Apex was programmed to turn on at 77 and off at 78.
Oct 6th, I noticed the temp spike to 79.6. Why didn't the APEX turn it off? Apex should've turned it off at 78, any ideas as to why?
Oct 7th, noticed that only one heater was working. Tried to turn on the other heater but it was dead. I turned of the outlet in Apex which probably saved my life. I ordered a replacement heater. I've owned this heater for almost a year but never used it until now.
Oct 17th, went to replace broken heater in sump with the new one. Reached in only to notice that the heater blew up or something but it separated into two parts. Counting my blessing that I didn't fry.
This weekend, I'm installing a GFCI outlet for the Aquarium. Currently where the Aquarium sits there isn't a GFCI outlet nearby.
thanks for the advise I just ordered a poly filter too and will install that as well once it arrives just in case.
Today my fish is also going in the tank, I have 2 clowns and a couple chromis that survived the Tank Transfer Method and its time for them to enter the main display tank.
On a side note, Dr Tims One and Only did not work after 2 weeks. One day with Bio-Spira my Ammonia was at 0 and Nitrite was close to 0 also. Dr Tims from Amazon might have a bad batch, I bought 2 bottles and both didn't work.
