Tank swap

[Deanster12]

Hi, I have just swapped to a 40g tank with a 15g sump, my original tank was 20g with a couple of clownfish, live established rock and about 3 corals. I have put new sand in and filled with natural seawater and let it warm up and settle overnight, 2nd day I added my live rock, fish and coral. I also added my filter media into the sump from my old filter with two caps of stability. Will this be okay or will it cycle again

It wont recycle. You may get some diatoms from the new sand though.
