When I was restarting my tank, I had to buy a new water heater as my other one wasnt working anymore. I bought the Marineland Stealth heater. It seems like when I put it into the tank a bunch of air bubbles formed on the surface of it... I took it out, wiped it down, and when submerged a few minutes later all the bubbles were back! Anyone know if this is normal or why its doing so?
I dont recall my last heater being like this, but it was clear, not black and maybe I just never noticed
