Scrub a dub dub

[seahorse11]

HI, I just bought a used 90 gallon setup. Some of the stuff has alot of crud on it and I want to wash it. Is there any cleanser that is safe for SW tanks that I could use? I want something also with some sort of an antibacterial just in case there was some disease that had been treated before I put the stuff in my clean tank. Thanks. :thinking:

Vinegar or a mild bleach solution, nothing else.

Is bleach or vinegar better to rid any residue of infection or chemical treatments?

honestly if the tank is all dried out there is no infection that I know of that can survive.
Bleach is a general all around disenfectant so if you are worried about that then use a bleach solution, I believe 10:1 ration of water/bleach is recommended, be sure to rinse well and let it air dry fully ( the bleach evaporates).
If the tank has been treated with copper then you run a "slight" risk of the silicone absorbing it then releasing it back into the water, but IMO that is a pretty slight risk, and something that can be tested for before you set the tank up fully.
