so im relatively new at reefing but ive done alot of research and ive mastered the first few months of keeping a tank

i have no corals, i have about 100 lbs of LR and the water is absolutely perfect.
am:0
nit:0
nitrate:0
PH:8.2

im just wondering, everytime i go into the LFS on their display tanks they have things that grow on the back of the tank and the returns... i believe they might be called pods?
lol
they look like barnacles
lol
anyways im just wondering why there arent any in my tank yet or if they will ever grow?

thanks guys and girls!
