Question for Won digital heater owners.

I cleaned a bunch of calcium buildup off the heater bar and when I put it back int the tank I noticed that when my digital readout said 79 the arrow on the dial cooresponded to only about 75. I checked the water temp with 2 stick on LCD cheapo thermometers, I don't even think my tank would run 75 with no heater because of the halides, mag and euroreef. Anyway should i worry about the discrepency in the dial or just rely on the digital readout.

did you have the digital readout model or was it the standard one? I'm not sure how they could stick on since they're digital and not the old fashion wiring which could malfunction and stick on but I guess anything's possible.

That makes me feel better. I had to clean my pumps yesterday and noticed there was a good bit of calcium buildup on the titanium tube. It was quite hard to get off even after soaking in diluted vinegar for an hour. I had to scrape it off with a knife and took about 20min, it was almost as thick as an egg shell.
