Why not put Oysters in a SW sump

[GoBigOrGoHome]

From what I've heard, although they can be effective NO3 removers, if they die, they decay incredibly quickly, not only releasing the same toxins as any other fast-decaying organism, anemone, clam, etc, but also all the other toxins they've absorbed throughout their lifespans. Depending on where they were harvested from, this could be anywhere from PCB's to heavy metals, etc...

Like I sead in posts be for I feed them to my triggers and I like eating them as well and your tank is a good way to hold them Iv did it with Lobsters as well

Normaly , for how much time do you keep them in your tank before eating them or feeding them to your triggers ?

Like you say GoBigOrGoHome they are just like clams I know that they will grow them out in the open waters. Its the hobby thats fun about it you dont know whats going to work and whats not going to and if some one dont try it no one will know haw its going to work for you and its nice to have more than one person doing it so you can campare
notes on what working for you ..

A few oysters can filter the entire tank in no time. At work we setup cloudy tanks with oysters and within an hour the tank is completely clear. They have filtered the entire water volume many times within a small amount of time. i am a marine biologist and co-workers setup this demonstration to show people how important oysters are.

As an undergrad, the lab I studied at had an oyster culture facility and I helped with an experimental oyster reef projects, so I've seen what oysters can do too. No one is questioning that. A polluted estuary or a turbid demonstration tank are entirely different scenarios from a reef tank though.

What happens to what the oysters clear out of the water? They eat the phytoplankton and then they turn the rest of the particulates into pseudofeces. Next time you run the demo for the kids, check out the bottom of the demo tank after it's been cleared. They're essentially a particulate filter that dumps most of what it filters right back into the tank, only as large clumps rather than fine suspended particulates. Most tanks are already low in particulates, and especially phytoplankton, anyway.

Oysters are also not chemical filters. Their only direct effect on dissolved nutrients is as producers, not consumers.

Again, it begs the question, what benefit are they providing in an oligotrophic reef tank and what is sustaining them?

Like I say I dont know the good or benefits of having them in the tank I like to see what you say about the particulates.
Imjust asking the Q?? Of WHY dont we (you) put oysters in your tank (s) dand that im put them in my tanks and I like to have a way to hold them and not haft to go to the store to get them when i need the and Im wanting to know if its good or bad to put them in my tank's I did not think out the way I wanted to ask the ??Q?? Sorry if Im coming across bad
