putting brine shrimp shells in display?

[chriss1992]

So is there any known downside to this nitrates phosphate etc? Could a display or the inhabitants somehow use she shells or should you really try to avovid getting them in the tank?

This works much better with decapped eggs (https://www.algaebarn.com/shop/live-foods/brine-shrimp/algaebarn-decapsulated-brine-shrimp-eggs/). Otherwise the egg shells are great for harboring bacteria and are very slow to break down.
