So I notice a little wobble from tank when scrapping the glass so had look about for why. Found that one of legs under stand ain't sitting right can see a bolt above rest but not this one like its collapsed so sound like I going to have rip tank apart as its 80
gal and over 350kg but lucky still got old tank and stuff but will give it a steam clean before use again. Can I just move rock,fish and water straight over and keep some of the other water to use when fixed and leave bit covering sand in tank will water in old tank be ok to use again as will lose about 40%
