Sorry to derail, but I really want to know why heaters are having so many problems...for most hobbyists, they are as essential a piece of equipment as a filter or light. Why are manufacturers not making them like they used to? Why is quality control no longer a priority with them They are an expensive, but simple to construct, basic piece of equipment. If they're going to charge $25 for an 100 watt heater, I expect it to work for a long time.
