Huge question, I am wanting to take the gravel out of my tank and replace it with sand what is the best way to do this without having to cycle the tank all over again?
Jarviek said:I did the exact same switch. I decided to change all of it at once, and my tank did not cycle after. I did keep a close eye on the parameters for a while after, and there were no issues.
