now my tank is only a few months old and I have kept two small clownfish, 3 soft corals. Have the red sea rollermate 500, I wonder if the rollermate takes away absolutely everything so there is nothing for the protein skimmer to pull out?

I personally would turn off the rollermat and consider keeping the skimmer on if you consistently get po4 reading of above 0.02, a skimmer helps with more than just removing nutrients, whereas a rollermat has too functions which it does extremely well, remove nutrients and keeps the water clear, but as said you really don’t need a rollermat with only 2 fish, you really don’t want dinos, get dinos and you will be praying for a tank full of algae.thanks for the tip, more fish coming soon. has 0 ammonia, 0 nitrite and approx. 10-20 nitrate, ph 8. turning off the skimmer asap
