Newbie here with some questions about my cycling tank

[Sumfingwong]

Sweet, thanks for the info.

As for sand, I will be going with no sand. Currently I have the 2 pieces of LR sitting on eggcrate.

I am also picking up 50 lbs from a fellow canreef member this weekend to add to the tank.

When should I do my next water change? I have not done one since I started the tank (only topped off the tank, because of the skimmer)

Here is a pic of what it looks like now. I added the eggcrate last night
