so I have 20 pounds of marco rock in my tank. right now i have 2 pounds of live dried out rock and plan to get 5 to 10 pounds of caribsea life rock. Tank is 6.5 months old probably. How long should I cure it and cycle it? Also I put some fish food in it and took out 11 or 12 pounds of my tank rock and put it into the bucket for beneficial bacteria. Any tips
