I don't care about growing pearls, but I am curious about the filtering help from mussels (or oysters if that's what we're talking about). I've seen vague comments about it around the forum but no detail. Anytime I can get a critter(or plant, etc...) to clean instead of me or a machine that needs power, I'm happy.

I know about marine oysters, they attach to objects and eat plankton. I understand freshwater eat algae. Oysters also filter about 50 gallons of water a day each. What I would like to know is where to buy them? When I Google search I only get oysters to eat or the same questions no one seems to know the answer to.

I live near a freshwater lake which has lots of little clams, as well as crayfish. I'm very wary of eating the clams though, as filter feeding bivalves accumulate toxins, and still/stagnant water bodies could easily have toxic algal blooms and the like.

I would also be a bit wary of eating bivalves from AP without using a UV steriliser to purge them of any potential nastiness like they do with commercial marine bivalves. But I wonder if they could be an additional food source for fish, and whether the fish would then end up with all of the accumulated toxins or not? :think:

They filter the water from dirt and algae. but do they produce any waster for the plants? That's the main question.

This they do.

It's a common misconception that they use nitrates, and compete with plants. Really they use suspended solids and excrete ammonia as a metabolic waste just like fish and crustaceans.

I had some mollusks in my green house for about a week. Boy do they stink.
