I have a Red Sea Max 130d and it has been set up for almost two years now. I started out with a bunch of beginner corals and have decided to step it up. So I took all my live rock out and sold it, my sand was dirty, so I decided to clen the sand, so I took all my fish out of the tank and put them into a rubbermaid container with pump and heater of course. The sand bed was so bad that I just decided to drain the whole tank and start over. I drained the water, tossed the old sand, put in new live sand and I went and got 30 gals of pre-made saltwater from my LFS. I also filled the tank with about 45 lbs of base rock. So my question is, will my tank cycle again? I mean this is just like setting up a new tank, I'm a little worried because I do have a few corals, fish and inverts in the tank. Would you recommend maybe some turbo start or something? Any help is appreciated in advance.
