Well since nobody wants to reply I will tell you what I learned. Yes they do remove all of the above. They use them to photosythesis food to grow. This is why they require light. In my opinion they would not be as effective as some macroalgae buy they still contribute.

Hello,
Wow that was a long time for a reply!

Tridacnid clams (if those are the ones you were inquiring about) are quite good at absorption of dissolved organic and inorganic compounds from the water column. This process is separate from the harboring of symbiotic algae however but is used to feed and increase the numbers of zooxanthellae if needed by the calm to meet its nutritional requirements.
Here is a link to one of the studies conducted.

At the end of the article there are other studies for more information. A search using their titles will uncover a wealth of information. Most of the studies are available on the Internet.

This link is to a study done using clams as the only filtration for a fish tank.
