hi everyone, i just moved and the old owners left behind their 75g saltwater tank. id like to convert it to a freshwater tank, but what should i do with the big rock? i dont want to just chuck it out, but also dont want to spend too much time trying to get rid of it because i need to move the tank.
there are no fish or anything living in this tank (that i can see), it just needs a good clean, sorry for the garbage pictures quality.
