Woke up this morning around 830 to feed my fish in my 75 gallon to find my Penn Plax heater had busted! The bottom completely busted out. Only about 6-7 months old. Thank GOD I have 2 heaters in my aquarium. I'm really irritated. This is my second heater to malfuntion in as many weeks. The first was a Marineland 75w that quit working in my saltwater tank after just 3 days, and now this one. That's it, I'm only buy eheim from now on. PFFFT:evil::-?
