Hello all, I have a question. I purchased 50lbs of live rock and added it to my 125 gallon saltwater tank. After a few weeks, tiny air bubbles appeared on the new rock and are starting to spread to the older rock. Parameters are fin except nitrate is a little high. I have a wet dry that I am in the process of removing the bio balls. I also have a 10-15 gallon refuguim. Any suggestions would be great. I will post a pic later.
