Non-submersible heater fully submerged....for 6 months.

[dutchswan]

I was cleaning my tank yesterday when I noticed little words labeling "maximum" and "minimum" on the top of my 300W Fluval heater. Additional research revealed that my heater is not, in fact, fully submersible. This may explain the following:
1. Why I thought I felt a low electrical current for just a moment the other day when I reached into my tank.
2. Unexplained deaths of 5 hermit crabs (usually 2 at a time) over the past 3 months.
3. My tank temperature hovering at 75 degrees while my 150W MH has been on all day...I am scared to think of how low the temperature was going in the middle of the night when the light was off!
I obtained a new 250W Marineland heater last night and was quickly able to return the water temperature to 79F. I am actually a little surprised my 3 fish, snails, and anthelia did so well for so long under this condition!
Thoughts?

My thought is don't use a Fluval or marineland heater long term. The fluval heaters are glass and are prone to breaking since they are brittle. The marineland heaters have a bad track record.

Well I just bought 2 ebo-jager heaters.....highly recommended by folks on here (LOL) they also have a min/max water line
BUT I WAS TOLD....they are fully submersible

my jeagers have been fully submersed.
I think you might be reading ti wrong Meo
its a Minimum water line. as in it has to be in the water at least that far for it to work properly.

We will see what they come up with.

I work at a pet store, and we FULLY submerse our "un-submersible" heaters with no problems whatsoever. They have been like that for almost two years now. They should be fine as long as the heater itself is sound.

welcome to the site Dertot!
I don't think we are questioning that they are submersible, just questioning why the instructions say they are not and there is a line on the product that says don't go beyond this line.
Almost everyone I know has at least one of these heaters and its fully in the water.
