Curing Dry Rock

[lpsreefer]

The last batch was just shy of about 150 pounds in a 100 gallon tub. I only did 5 gallon change every week, but the 5 gallons was from my main tank.
Bacteria still needs a food source to reproduce or spread.

You don't really have to do water changes all that much as you want bacteria to grow and there is no light for algae.

If after your first week in saltwater. If all your tests come out zero, then I wouldn't do a change for a few weeks. If your po4 is high then do a big water change as te rock is leeching.
