Stay away from Marineland Stealth Pro heaters, they are defective. The ones with black rubber coating with epoxy inside and LED lights. Had mine for two weeks and two nights ago it split open leaking some sort of lubricant into my reef tank :WTF:. White smoke, like fog but smells like burnt rubber, was covering the surface of the water. My entire room stunk. All my corals, live rocks and live sand died off. Had a fish ($80 Desjardini Red Sea Sailfin Tang) also die from the contamination. I have to throw all the corals, live rock and live sand away. That alone cost me at least $700. Managed to save the rest of the fish but they don't look like they're going to make it
