it is hard to keep the regime going, dont i know it..
she is at a stage where you need to act, do you have a spare tank? if so get the affected fish into quarantine as they will have a very low immune system and any parasites could be in the water column. water change, water change water change.. the biggest you can do now

and clean that sponge
Get them into a QT, doesnt have to be to big.. but get them in there and away from healthy fish..
can you list your water params please and fish/inverts you have in there at the moment?
give your LFS a call and see if they can get wormer plus for you quickly.. its surprising how fast and hungry they get after a worming..
