Upgrade NanoCube28g to RSM250 - Aquascape Question/Feedback

My recommendations won't help you avoid inevitable diatom or other similar issues, but it will ensure you have no losses due to a cycle

Something such as this
Just ensure the contents of whatever you buy is only ammonia and water.
Absolutely nothing else.

Thanks for the advice. I'll be limited on time but I can probably keep both tanks running for about 2 weeks in parallel before taking down the NanoCube 28g. This should hopefully help keep everything steady and stabile.

Also thanks for the term "mulm". In past I had spent some time trying to identify the grey curtains of dust that build up on or under rocks.

Just to clarify, you don't need to keep both tanks running parallel with my suggestions. You can do a one-day transfer if you;

Cycle the new rock in the tub and complete the probably 4 week cycle.
At this point you can start the new tank with the newly cycled rock.

Then you can deal with the old tank and rock at your leisure.
