I just picked up a 180g acrylic tank. It is approximately 18 years old and has a lot of built up calcium from it previously being used as a reef tank. Can anyone give me some pointers on cleaning this tank up. My plan is to use vinegar and a semi abrasive sponge to remove all of the buildup. Then if the tank is really scratched up I will wet sand and polish. Is there anything I am missing? I can’t wait to get this thing up and running. cheers
