I have acquired a 29g tank from my brother. He was storing it in his garage for the last 3 years. He used the tank for a saltwater aquarium (fish unknown, he does not remember what he had). He claims that he discontinued the tank due to a black mold issue?? I did not realize that saltwater could have black mold inside the tank. (Forgive me if my knowledge is less than
par). Now looking at the tank sitting in my living area, I am concerned that even with cleaning the tank out, and testing it for leaks, this may not be a good tank for future inhabitants.
So two questions:
1. Is there such a thing as black mold issue in saltwater tanks, or was he mistaken for an algae problem.
2. Because the tank has been out of commission for so long, is it still safe to use (after passing a leak test)?
Thank you for your advice in advance.
