looks like i should get a clam when my tank is ready
If your set up sps, go slow, 1 oyster for every 10 gallon? I use in nps tank so different. Have in mesh plastic bag for few weeks to see if any die off. See videoYou got me interested as well. One could possibly supplement refugium sump with a few oysters? Do they require anything besides being in water? No light required? The reason I ask, is that I'm thinking on adding a few in my skimmer compartment, after my refugium.
(1) Do you have any concerns about Oysters spawning in your system? The following quote is from Wikipedia: "Oysters usually reach maturity in one year. They are protandric; during their first year, they spawn as males by releasing sperm into the water. As they grow over the next two or three years and develop greater energy reserves, they spawn as females by releasing eggs. Bay oysters usually spawn from the end of June until mid-August. An increase in water temperature prompts a few oysters to spawn. This triggers spawning in the rest, clouding the water with millions of eggs and sperm. A single female oyster can produce up to 100 million eggs annually." I would think the high volume of gametes in our reef tanks could cause havoc...
(2) On your preference for Pacific Oysters, do you have any preference for oyster types? There's an Asian Market close by, but I think their fishmonger's English language fluency is about as good as my Chinese fluency. I have found a source in central NJ that is within driving distance for me. Their web site infers their oyster bar has the following oysters available (depending on market conditions):
Totten Inlet (Wa)
Hama Hama (WA)
Beau Soleil (NB Can)
Blue Points (NY)
Ichabod Flat (Mass)
Island Creek (Mass)
Lucky Limes (PEI)
Puffer Petite (Mass)
Rose Cove (NJ)
Sloop Point (NJ)
Sugar Shack (NJ)
Wilding ******** (NJ)
I think your choice would be for Kumamoto, probably just for the latitude of the source's location. They are apparently a smaller variety of Oyster, originally from Japan, but I don't think that would make any difference in the long run.
(3) I'm not sure your reference to "pseudo feces which will feed the corals" is technically correct. Here's another quote from Wikipedia: "Pseudofeces or pseudofaeces  are a specialized method of expulsion that filter-feeding bivalve mollusks (and filter-feeding gastropod mollusks) use in order to get rid of suspended particles such as particles of grit which cannot be used as food, and which have been rejected by the animal. The rejected particles are wrapped in mucus, and are then expelled without having passed through the digestive tract.  Thus, although they may closely resemble the mollusk's real feces, they are not actually feces, hence the name pseudofeces, meaning false feces.". I think my corals would prefer real feces to grit .
Thank you Dr. Dendrostein for leading the charge into this new filtration arena of Reef Keeping ! ! !
I feed continuously, and no break outs of aptasia and no hair algae. I do light one sump with natrual sun light. Also the 7.5 nano has nps and photosynthetic softies and no aptasia break out or hair algae.....etc.That’s great. I added a couple of Squamosa clams to a frag tank and whether a coincidence or not, the hair algae issue cleared up over the past couple of months.
Kumamoto, should be pacific oysters. I've tried other types and I've noticed more success with Pacific oysters. The advantages outweigh the disadvantages. I've had oyster spawn on me and the corals love it. You have to realize my system is NPS and so it's able to handle considerable amount of feeding. Anything else like SPS or LPS I can't say. Also consistent water temperatures is very important because if temperatures fluctuate you will get more spawning. I say that from others who have tried oysters in there NPS system but the filtration not design for the extra organic matter. All I can say is if you have SPS or LPS corals go slow and start with a small batch of oysters. Maybe one oyster for every 30 gallons. Increase lowly. My thoughts
