Hi everyone quick question so I am looking to upgrade to a new reef tank and sense I am a 13 year old I need some extra cash and my old reef tank right now I am going. To sell to cover the new one it is a 25 gallon innovative marine laggon with white stand and no leaks and the stand it only 6 months old and a protein skimmer. I am just wandering how much should I sell it for a fair price tanks everyone.
