live sand/cycling question

[crabman]

Be careful mixing new and old sand, especially if it is of different grades. We just upgraded and experienced some of this. The heavier/larger sand will sink to the bottom, giving it a striated look.

We used Fuji Pink Sugar fine live sand. It is bright white sand. We have a Diamond Goby who works hard and doesn't create a dust storm. We recommend 2 20 pound bags of live sand for your size tank (we were recommended 1 pound per gallon), depending on how deep you want your sand bed.

thanks for the advice! we're definitely not going to mix the sand at all, just want to start fresh with all new sand. any ideas about the cycling situation? lmk, thanks.
