I'm upgrading to a 260L tank and closing down my 180L tank.
I've not done this before so I'm a bit stuck on the best way to do it.
Do I add the old tank water into the new tank or set it up with clean water?
Do I run both the new and old filters in the new tank for a while? Or just add old media into the new filter? Or can I squeeze out my old media into a bucket and let the new filter suck it up?
