Not everyone needs to feed their corals, but some do with various additives. Some people are lucky enough to have just the right balance of nutrients to feed their corals "naturally" while still maintaining a low nutrient system. Some people are not so lucky.
Biopellets don't consume calcium but the bacteria which you are growing on the biopellets can deplete essential nutrients that corals would use to grow. For example, some corals need trace amounts of phosphate to grow. It's quite a delicate (and difficult) balancing act.
I do not feed my corals anything but did notice a slow down in growth when I cranked up the amount of biopellets earlier this year. I have since dialled them back.
Also, keep in mind that even if your tank on paper is identical to someone else's tank, chances are the make up of your actual tank water can be dramatically different. As a result it is very hard to compare two tanks this way. You both would likely have different organisms doing different things to your water chemistry, not to mention a crap load of other factors (equipment, age of system, husbandry, etc).
