Switching tanks. What to do?

[FishNutzBoi]

Im in the process of replacing my old, scratched up 75G tank with a new RR Oceanic 75G. I have a few questions:

Im planning to replace the sandbed:
1. What grade should I buy? Fine, medium, large? I want to be able to keep some kind of barrow or sandsifting goby so I was thinking of going with medium or large to avoid sand flying around. Is there an advantage of having fine sand?

2. How many pounds of sand do i need to achieve a 1 - 1.5' sandbed in a 75G?

3. What's the best/most used brand of sand? Why?

4. Since Im replacing the sandbed, would I need to re-cycle my tank? I have about 160 pounds of cured LR.

My tank should be here in 2 or 3 weeks. I took all my fish to a LFS. They are staying there til I finish setting up the new tank. Right now. Most of my LR is in a 29G and a 5G bucket. Im placing the corals back into the 75 once the water is cleared up so they can get some light.

5. Can I keep the LR un-lighted in the 29G? Any problem if i do this?. I don't want to move 160 pounds of rock back then out again once the tank is here :/.

That's all, FOR NOW :lol:

Thanks in Advance

I personally just bought a bunch of different grades at my LFS. It might say on the bags how much area it will cover (or just imagine the bag sitting in the bottom of the tank). There is a sandbed calculator in the RC homepage.

I dont think you need to re-cycle the tank. Save the top layer of your current sandbed, and add it back in top of the new sand. The LR will be fine without lights.

The reason y im not using the old sandbed is b/c it's full of detrius. The top layer is worst

Thanks for the tip on the calculator
