how to cycle dry rock

[jelly]

my tank is being taken over my mojanos, mushrooms and brown/ green zoas.. i have tried a lot of things to remove them but they never stop coming back and im sick of it.. now i want to replace all my LR with new rock from BRS. how long should i cycle dry rock for before i switch the rocks out.. whats the fastest way to get the dry rock to become live with bacteria and all crap out of it.. it will be mined dry rock from BRS. once i have the rock switched out whats the best way to nuke the old rocks so it kills everything and then recycle. im going with 200lbs of dry rock in a 180 tank..

thank you

Switching the rock is pointless. All those things will still be in your tank and grow back. For it to be effective, you need to drain the tank, remove the rock and sand, clean the tank, and rinse the sand (or throw it away and get new sand).

Which rock from BRS? You will need to cure all of their dry rock except for Reef Saver. All of their rock (and every other supplier of dry rock) needs to be cured due to dead things that have dried up in the rock. Reef Saver is dug from ancient reefs and then powerwashed so there is nothing in it.

For any new tank, I use reef saver rock + Caribsea Seaflor Sand + Dr. Tim's Bacteria. My tank cycled in 2 days using it. You will need a small piece of live rock from a tank that is known to be pest free as possible to introduce algae and other things to make the rock become alive.

You will need to give your old rock an acid bath if you want to reuse it.

If you don't have pest free live rock, you can use a raw shrimp from the grocery store. Might take a bit longer to cycle though.
