Actually it is pretty stable. Well as far as the filter that is attached on the back should I remove the ceramics and the bio balls and just run the carbon and the foam?got water/salt mix in there yet? If not this is your first step. Then once this has mixed add coral sand, ones salt levels and temp is stable add live rock, wait until algae bloom, add clean up crew, then leave for 3-4 weeks until water is stable.
That stand looks very weird not sure if i would trust it lol!
