Upgrading Tank but Current Tank Has Cyano

[Fumbles]

I have a 32 biocube and I’m planning to upgrade to a 90 gallon(I have all equipment, just needs to be plumbed and water tested).

My current tank has had a Cyano problem for the last 3 months. I think from a few things(lack of flow, not enough water changes, not enough sand syphoning). I did the peroxide test and it was unaffected, so I think it’s actually spirulina. Tank is about 9 months old.

My question is, how do I go about moving everything over to the new tank with the Cyano? Should I fix the issue before moving everything over or deal with the Cyano in the new tank?

I plan to keep all my live rock and use new sand in the 90(seeded with a little bit of old sand).

You have to think about how much trouble it is because most likely no matter how much you "start over" to avoid it you're probably going to end up with it again. If it were me i'd figure out my strategy for getting rid of it/preventing because that just comes with the hobby.

So are you saying to plan on it coming back/staying after the upgrade and deal with it in the new tank?
