Well it's kind of hard to give anything precise on the date right now but things will be much clearer when all major 3rd party work is over since that has been slowing this down the most.
My friend is building a frame for the lights and another friend is doing the overflow boxes. I will also start the plumbing very soon and the sump will be going in the fish room as soon as the contractor finishes the floor there. Can't wait to test out the circulation from tank to sump and vice versa.
I have also been reconsidering how to cycle the liverock. I think that rather than putting the rocks in smaller containers and then to do aquascaping in a stressful rush to keep it from drying up again I will rather just do the aquascape slowly, dry and carefully in the tank and then cycle it there when it's just the way I like it. I think the quality of the aquascape will be worth the few $ saved on salt mix.
