I have a 29gal tank with a 20gal sump below. I just got it running 2 days ago and it’s bare except for some matrix and a filter sock. I also have a skimmer running just to break in. I’m picking up 40lbs of live sand tomorrow along with some chaeto. I have a Mars aqua 165w coming in on the 16th and until then I just have a cheap full spectrum led for DT. I’m planning on getting 40lbs of live rock from KP Aquatics. Should I wait for the new light to come in or will it be fine with the cheap one until the new one comes in? Can I cycle the tank with the live rock (Just chuck it in when it comes in) or should I cycle my tank with the sand first and then live rock? Here’s a couple pictures of my set up just to give you guys an idea. Any advice on cycling and just anything will be very helpful as this is my first reef tank and I’m learning a lot as I go.
