I just had a heater emergency

No, in fact the heater is positioned under my filter so the water flow is easily distributed over the heater to make for more even temps in the tank. The top of the filter is about 5 inches under water.

Hey Inga,
Do you still have the defective heater? I was just reading a thread on another forum about a problem with the Stealth Pro heaters exploding. Apparently there's been more than just one instance and it did some damage to some tanks. If I were you I would call Marineland and tell them what happened. They should replace your heater (although I would be nervous about the dependability of these heaters). This is really a shame as Marineland used to be a top notch company but they are having issues now with quality in their heater line.

If you still have your defective heater look for the lot# on the neck of the heater in white letters. The affected lot# is 01H31. This really has me nervous as I have 2 of the Stealth Pro heaters and another one on order. The older style Stealth (without the red/green on/off indicator light) is not affected. It's just the new Pro series.

There is an ML # 90453 and at the very top part a small number that is 01l31 it doesn't say "lot number" by it though. I am really mad about it because it is so new but I am not so freaked as to not use the product again. At least, I wasn't. If enough people have had this issue, that isn't good. I think there is room for error in any product. I did purchase another of the same kind because I have heard so many wonderful things about them. I thought it was just a fluke and I was the unlucky one to get that faulty one. I certainly hope that is the case and won't repeat this problem.

I do intend to call Marine Land though last time it was a lesson in frustration. I was calling to find out what the K rating was in the stock lights. They acted like I was speaking a foreign language and then sent me to voice mail of someone who was on vacation for a few weeks. I left my name, and number and they never returned my call.

I have heard that other heaters when they break down tend to not shut off and basically cook the fish. This one is supposed to shut off when the temp hits a certain amount. Safety feature... Might now be worth much if the stupid thing explodes instead.
