Does this mesh ball topiary thing work?

Does this kind of mesh topiary thing work with your Chaeto, Mustafa?

Hmmm...it *should* work as the macroalgae will just grow through the holes but you'd have to take out the "topiary" and trim it outside the tank as trimming it inside would release a huge number of fragments everywhere that would be a pain to deal with. If you try it, let us know how it goes!
