how to clean an old tank

[Hungriee]

Im interested in buying an used tank, whats the best way to clean the tank? It smells like an ocean :wink:

There are lots of gunk on the glass, whats the best way of making it crystal clear again?

vinegar

white vinegar

I would fill the tank with fresh water and a depending on the size of the tank 1-10 gallons of white vinegar. Let it sit over night. This will dissolve the calcareous algae as well as leak test the tank.

after filling and washing w/ vinegar and fresh water - how would you know to rinse it enough so there is no more vinegar left for filling it w/ salt water?

I would just do a quick rinse with a hose. Then let it sit for a day or two and I doubt you would have anything to worry about.

agreed any left over residual vinegar will only lower the ph a small amount
