Yes, it's the Hydor ETH 300. It's hooked up to my XP3 output. What happened was when I was doing the PWC
, I also did filter maintenance, which I usually never do at the same time. I normally do my PWC
with the filter running, thus water keeps flowing through the heater. And when I do filter maintenance, there's always water in the output, as the spraybar would always stay below the waterline. Since the output of the filter was stopped and had no water from the spraybar being out of the water, the water got hot fast and started boiling. I quickly shut it off. As for now, it seems to be working fine. It's maintaining the temp properly. But I'm going to keep a close eye on it for a while. Don't want to take any chances.
