That sounds like a great plan to me. Thanks for all the advice. I hope to get the new tank set up with all the plumbing in the next couple days
At what point am i most likely to start a cycle in the tank?

You shouldn't get much if any of a spike. The llive rock that you have in the tank should be able to handle the bio load that you transfer over.

Hey guys so I finally have everything almost ready to transfer. It's full of water. Temps right and salinity's right. I just decided to put my sand in and now it's extremely cloudy. I went with sugar sand and I'm starting to regret it already. I don't know if I'm over thinking this but I feel that it's going to blow around. U could be wrong though. Does anybody have experience with this. Hoping to add everything from my 55 as soon as my tank clears up.

So how is the sugar sand turning out? Still regret it? I'm getting my new tank in January and looking for info. Love the look of sugar sand, but wondering if it is impractical. I'll be keeping a mixed tank... SPS, LPS and zoas

I love the sugar sand and it turned out great. At first i was kinda regreting it but after two weeks my water was nice and clear. I have 4 korallia 4s and 2 korallia 3s for flow and it doesnt kick up sand at all. I have a mixed tank as well

Thanks!
I'll be running 2 MP40s. I wonder if that will be enough in tank flow for a 74g (36x18deepx24high)

2 MP40's will definitely be enough flow for your 74g. I'm running two on my 125 (60X24X20) and its full sps and everything is doing great.

That will be tons of flow. Its higher then most so i dont think the MP40s will have much effect on the sugar sand. But again it depends on your scape and the height of your MP40s
