So I just returned home from a 2 month work trip to find my 40 gallon salt tank with 95% of the fish dead and bristle worms every where. I am pretty should my parents over fed the tank while I was gone, but the main problem is the bristle worms, there are so many of them. What should I do should I take time to slowly remove them til I get their number to a reasonable size of should I just redo the entire tank?
