What adds to bio load??

[Biocube14]

I currently have:
2 true percs..
1 coral banded shrimp
2 camel shrimps
4 hermits
6 snails
1 royal sea urchin
1 coco worm
Misc corals..
About 10lbs live rock
14 gallon biocube..
Nothing looks crowded. Fish are happy/mating/eating..
My question is what is adding to the bioload other than the clowns??

Everything is adding to the bioload, just some more than others.

All of it. If it metabolizes fish food or algae, it is adding organic waste to the system.
