Today my heater broke in the sump. it started smoking and all the corals look pretty bad. But the fish and shrimp look fine. does any chemicals get in the tank when this happens or is just like a electric shock or just smoke lower ph. What should i do. I removed the heater. Should i add carbon. I just added a frag tank to the system today so that added 30g to a 90g tank. Please help. Oh yea. I have a second heater in the tank so that is not much of a issue
