I just bought a used 90 gallon tank with a stand, 2 heaters, return pump, wet/dry trickle filter and some lights that I know will need upgraded eventually. This is my first foray into salt water tanks, so I am not sure of some things. I know the stand needs some minor repairs. Not a problem.
However, the tank had been sitting for about a month and I dont have any idea what was in it before, so I want to clean it before putting anything in it. There was some water left in the trickle filter and it has all turned black and looks/smells bad.
What can I use to remove the salt buildup and the other gunk from the tank and trickle filter to make sure I dont introduce anything harmful into the tank when I put it together?
