    looking to downgrade..

    Im looking to set up my 20gal Nano again and take down my 75gal reef.

    gonna turn my reef tank to FOWLR.. or even 1 blue spot sting ray.

    anyhow.. can i just setup 20gal add new deep aragonite sand bed and add water rocks corals and fish from main tank?

    and be okay? no cycle?

    also thinking of drilling 20gal and making a 10gal sump to go along with it..

    With a new sandbed, I think that would cause a cycle.
    My opinion of-course.

    Why ask the question when you already know the answer then?

    Hmmm, the "cycle" word again. Never liked it because it seems to be used for many different things.

    What do you mean by cycle?

    Will it take time before it can support a bioload? Yes. But, you will get some filtration from the rocks right from the start. You shouldn't add a full bioload right away.

    Will it take time before the starfish and various pods populate the sandbed? Yes. But, this time will be shorter when compared to a wholly new setup. Still not instant.

    Will you get an Ammonia spike, followed by a Nitrite spike, followed by a Nitrate spike? Not likely if you are using fresh clean sand to start with and the rocks are never out of water for more than a few seconds.

    Can you ever rush a salt water tank? Yes. But, with risk added.

    I hope this helps.

    IMO the best way to do this is to set up the nano and connect it to the 75 for about 30 days so the 2 tanks function as one. If you can do it that way there will be NO cycle. The new sand bed can be seeded with some sand from the 75. Put what you want in the nano from the get go and treat the 75 like a VERY BIG sump with a sand bed.

    I set up a 32 gallon tank 8 short days ago. The substrate is new, but the live rock, filter media & 3/4 of the water came from an established tank. 24 hours following set-up I added a hippotang. I've been monitoring the water closely, and so far, all is well. = )
