I have a 30g tank with about 20lbs live rock and i have been noticing there are tiny white specks on the coralline algae, mostly on one rock.
The coralline algae on the other rocks have white around the edges and some of it has a thin almost transparent layer on them. I have read that the white around the edges is new growth, is this true? What about the thin tranparent layer on top? Should i be worried about this?
I drip a gallon of kalk
for refill every two weeks, with 25% water changes in between.
Sorry no pic. I need a dig. camera!
Any help would be appreciated!
