I would suggest long term getting a better fert system but osmocote+ is a little ball of some kind dipped in fertilizer. So the little balls will never go away. The fertilizer on them simply releases into the substrate (where people usually put them). Regardless of where you put it it will end up in the water column all the same. Just because the substrate seems like a barrier, it's not. Water passes back and forth through the substrate. Just take the capsules and put them in the substrate to the glass. The cories shouldn't dig that deep. Your plants will benefit all the same.
