Does anyone have an idea what the round dots are appearing on my rocks. Some are on the mushroom frag and several on the rock to the right of the mushroom frag . I also have some on the back glass. The pictures make them look blue but in reality they are more milkish white in color and appear to be more of a bump or growth. I have some coralline algae growing but that is flatter in appearance. The tank is 120 gallons and approximately 9 months old.
