So my and a friend were eating just chilling next to my tank...and my friend asked me the question "would a couple of dimes and pennies destroy the whole tank"?.....i was also curious 2 since i know copper in any reef tank would lead to disaster....So my first question is....will Coins in particular or any other metal objects destroy a tank.....and my second question is if a really small amount of oil is dripped in your tank would it destroy the tank 2? i heard that a drip of oil in the ocean destroys gallons of water.....:Thinking: :bablefish
