How much live rock is ideal to seed an otherwise dry rock tank?

[a1abeach]

Well here’s my question I have caribSea’s rock in my tanks for five months I want to add live rock to see existing CaribSea’s rock will that helps diversify my CaribSea’s rock?
And how much would I need for this tank?
I do have corals and fish in my tank at this time.

Logically speaking, you can seed 1,000lb of dry rock with 1lb of live rock as long as you provide the food and environment for the bacteria. I don’t know about marine bacteria, but all other bacteria reproduces at a rate which makes getting large amounts of live rock seem silly.
