What to do?
So, I have an empty 12 gallon nano cube, a half open 25 lb. # bag of sand, 15 pounds of rock that has been dry for at least two weeks, and 10 gallons of dirty water from my main tank (that was taken out during a water change). Is their any way that I can use all of these elements to get the nano cube up and running again. Should the dried up sand, dirty water, and dead rock be enough for a cycle to occur? I want to start another nano tank so any recommendations would be greatly appreciated. TIA........
