I don’t know the exact dimensions I just know it’s a 125 gallon long. The friend I’m getting it from his wife use to manage a salt water fish store,so everything was cleaned and stored properly. the water features will be removable and self containing so I should still be safe. I plan on a uth and probably some lights of some sort due to PA being cold I’ll need something. It should be a fun project that I can take my time get it running and make sure everything’s safe before the big move
