What About Freshwater Clams?

What about freshwater clams? I heard they clean up your water?

These "rocks" - e.g. are enjoyable residents of the pond, and are hardy.

But there are catches:

They have to eat, and as filter feeders, they thrive as long as there is a macrophyte bloom. In green water, you can't lose one. In crystal clear water with UV in place, they starve to death within a week or two.

They're also sensitive to 100% of what will kill parasites except Dimilin. (They survive this) So when you Salt, Fluke Tab or Potassium the pond, and anything else, the clams are goners.

In fish tanks, you want aerated, well circulated water which is cool (seventy DF) , and you can feed them pureed fish food enough to cloud the water. Or let the water go green and they are happy too.

The Calcium of the water must also be supported to at least 80ppm . IN very soft water their shells will become pitted and nasty. In harder water, growth is enhanced and their shells look nice and green.

I have kept clams as a kid quite a bit.

They are not intermediates for anything you might worry about pathogenically in North America, however if they are kept with fish at the pet shop, the water they come home in might be infectious.

Therefore, since they cannot be chemically decontaminated, you should simply house them alone (fishless) for 14+ days before introduction in the pond. Without a FISH host anything they might have adjacent or symbiotic to them will be "spent" and the clams "safe"

I HAVE YOUR BOOK.....AND NOWHERE DO I SEE THIS.
I HAVE TO ''SALT'' MY POND.....I CAN PICK OUT MY POTTED PLANTS....NO PROB.
CAN MY TRAPDOOR SNAILS AND FRESH WATER CLAMS TOLERATE THE SALTING?
THANK YOU

Freshwater clams love to die anyway and are not often kept in tanks or ponds, I like them quite a bit though and when I had some with a Giant Goramy, I salted and they did not care. 0.3%

Trapdoor Snails, same thing, but I only ever did those up to 0.3% and gradually (applied in thirds every 12 hours to 0.3%) with those too.
