I've got a mixed reef with SPS and Zoanthids, but I'm worried the Zoas might mess with the SPS. Anyone have experience with this combo? My tank's a 75-gallon with Radion lights, 1.026 salinity, and weekly 10% water changes.


It depends on the Zoa species. Some, like Rastas, are pretty tame, but ...

Yep, play sand's usually fine if it's pure. I've used it in my 55-gallon for years with no drama. Just rinse it till the water runs clear, like you're already doing. Bonus: it's cheap as heck.
