Hard white crust??
Posted: Sat Jan 19, 2013 4:27 pmMy in tank heater has a layer of hard white crust on it, so I took it out to clean and realized my habitat spray doesn't work on it.. Now what?? It's all dried now cause I've had it out for a while but I'm not quite sure what to do to clean it? I tried to google it but couldn't find anything
