1. I keep reading mixed advice re. whether to cycle with just live rock or to cycle with rock and sand together. Thoughts?
2. Recommendations for sand? I saw live bagged sand at petco. I prefer finer sand to coarser material, though obviously want what's best for tank.
Thanks!
Welcome to reefing jdl.
I went, and did a quick look over your previous thread. All of your questions were answered.
Your not really getting mixed advice on how to cycle your tank. They have told you that there are different ways to cycle a tank. Bottom line it is your tank, your choice of which way you want to go.
If you are going to use both live rock & sand in your tank, then go ahead and cycle it with both.
If you do not intend on using sand (some people prefer a bare bottom[no sand]) then you simply cycle your tank with the rocks. Live or dead rocks is fine also.
You also do not have to cycle a tank with a piece of shrimp in it, you can add a tiny pinch of fish (flakes or pellet) food.
I cannot help you with a nano, I have never owned one. Smallest I had was a 20 gallon tank. All I can tell you is that you have to stay on top of small tanks because things can go wrong in all tanks, but it can be devastating to a small one.
As for what sand to get, that again is up to your likes.
I can tell you that you do not need to buy "Live Sand".
Also, be very careful on who's advice you take. Some come across as very knowledgeable but in fact do not know much.
