Oysters as filter feeders?

This is actually a cool picture, unfortunately I don't think oysters can be acclimated to warn water.

Yes, a buddy of mine who used to be a diver used oysters as filter feeders in his large tank. He used an old refrigerator that he modified as a chiller to house all sorts of cold water fish & inverts.

I believe giant clams function similarly. There’s a thread here where the owner of a gigas tore down his old tank, the put up a pair of tanks on either end of the room with the gigas in a central tank and he (she?) can hardly keep nutrients in the water.

Yeah - he has a crazy super awesome large clam. Video shows him upgrading tanks and I think he said it was over 26 lbs.

If you are talking about your store bought fresh ones on ice the answer is yes they can survive just fine in a reef tank :) I wouldn’t class them as useful though. I have 3 in my tank that have been there for around 6 months.

I actually experimented on this years ago. My brother in law was working at a catering company and brought me live Chesapeake bay oysters on ice one night. We SLOWLY acclimated a half dozen or so to my reef tank. They lived a good while actually but in the end perished because I couldn't keep them fed in a relatively low nutrient system. With the ability to sustain their nutritional needs, they could absolutely live in a reef tank

What is "slowly?" Hours?

Yea I used an airline tube with an adjustment valve and dripped the tank water on them at the slowest rate possible, if I had to guess I'd say like a drop every 5 seconds maybe? Regardless of that I drip acclimated them for 4 hours. I would say it depends on what condition they are when you get them though. I live 45 mins from the Chesapeake bay so if I were to say get them directly from the bay they wouldnt need as much time. But when I got them they were literally on ice so I needed to bring them up to temp as slowly as I could possibly,manage.

I have 60-65, in my outdoor refugium. Need them for nps tank . DT small but does the job. Trying to raise Dendronephthya. Have some clams. I recently spilled a lot of coral food. NO3 at 5ppm was a lot higher . Coming down. Before spill. NO3 at 0, no matter how much food feed. Depends on tank design
