Ok here it is. I have a tank set up right now and i have just bought a bigger tank. I want to reuse all the stuff i have in old tank includeing substraight. How do i go around transfering. Only main reason why im asking is im concerned i may disrupt the substraight and end up with a major amonia spike withing new tank or in process when removeing substraight i might kill off some of the nitrafieing bacteria. Could you exsplain the best way around this. I googl;e and found not alot.
