This year I felt it was time to start replacing older heaters in the tanks. I've always used the Marineland VisiTherm heaters without issue. They kept the tanks at the temperature I wanted with accuracy. I have two of the newer, made in China now, 300W heaters in my 75G tank. I just noticed my tank water temperature is 70F, not 80 which is what it is supposed to be. Both heaters are still coming on. They've been at least 4 degrees off the set temperature from right out of the box. So I just adjusted the thermostat to correct that difference. It's just been somewhere in the last couple of days that this temperature drop occurred. These heaters are guaranteed for life.....but I really don't want them anymore. I don't want to have to worry about cooked or cold sick fish. Are there any dependable heaters (not in-line) that someone can recommend quickly. I'll speak to Marineland tomorrow, see if I can get my money back for this garbage and need to get something else. So tell me about the heater you recommend. I'm looking to hear about heaters that have been purchased within the last year since your older heaters may no longer be made the same today.....like the Marineland line now!
