How do all?
I'll be switching tanks next week and have a quick question about the substrate. Should I transfer all of the sand from my old tank and mix it with the new sand or should I only put a couple of cupfulls in the new tank?
I'm sure I read somewhere that it shouldn't be all of it?
Thanks v much
