Setting up new tank. Usinf old tank

[marcusreaich92]

Hi guys, new to this forum. A quick intro been in the hobby 2.5 year with a 13.5 gallon evo. Now purchased a d-d reef 600.
My evo had one BTA which is now turned into 15+ it’s booming I have green gsp on walls and that’s it pair of clowns.

my ask is. How do I set up my 215 liter tank?

do I have to fully cycle it? Or could I use my old media and a drop of bacteria and change tanks? Thanks

What's the size of the new tank? Yes, you can potentially insta-cycle the new tank using your existing rock.
