About the oysters, when I returned to reef keeping 10/2017, my goal and still is, to try aquaculture of NPS softies, eventually I think since bans, these species will disappear from our hobby, when? Eventually and soon. So I first did my homework, alot of reading on these corals. Still at it. So 10/2017, I setup my tank, and two outdoor refugiums. As summer came in setup a chiller, but before summer, I read oysters the most efficient natural filtration system in the wild, for being a creature. They can also remove nitrates, ammonia, and more. When it comes to healing a bay, oysters are implemented. And if conditions right spawn, food for corals.
So, I wouldn't buy tropical oysters too costly. I read about Pacific oysters, very hardy. So tried them from different markets, eventually found from Asian market Azul Sol, from Baja California. They come in plastic mesh bags. If you try them, I recommend very large filtration, I'm running 16 gallon DIY filter canister, inside it 1 cu foot of activated carbon, then ran through calcium carbonate grave in my case limestone, then back to DT. Large filtration, why? You may have a die off. They also need continuous micro algae. From die off if some do, you'll be left with hardy ones.
The outside refugiums had 80 oysters, 3 abalone, 10? cherry stone clams, chaeto, plenty algae,,good and bad.
