Hi everyone. I need some help, I am set up, 90 gal., 100 lbs. Marco Rock that I have aquascaped, 120 lbs. Marco Sand. I have put raw shrimp in to start the cycle, it has been about 4 days and amon. is going up slowly. My question is should I put some live rock, not much just to seed and sand in now while it is cycling or wait. I plan on going to the meeting on the 23 to meet some of you. I was hoping someone may have some sand and rock for sale. Thanks for any input.
