    I've been considering a clam for a while now (probably a Deresa), but I'm waiting until I find a "pretty" one (My wife likes to help pick these type of things out). However, I've been doing some reading on clams and what is needed to keep them healthy. I've noticed that several articles say that clams will lower nutrient levels in some tanks because that's what they mainly feed off of once they are bigger than a few inches.

    Is this true - do clams really lower No3/Po4 in reef tanks?

    I've not heard that directly. But most photosynthetic animals will lower nutrient levels as the photosynthisize. Ie. having a lot of corals will lower nutints in a tank.

    I don't have the links handy. But if you Google James Fatheree and clams you'll get a LOT of really good info.

    And if you visit Aqua SD they have about five amazing derasas in stock. Super super healthy. About four inches. I saw them in person.

    Though most don't agree that it's necessary, we feed phyto and pods to our clam dominant tank. These beautiful creatures filter the water in the ocean thus getting an additional supply of food through their filter feeding as well as the sunlight. Just an opinion. Clams do reduce nitrates. Again, google James Fatherree - it's a great read.

    In our closed systems it's not going to be a lot. Clams get their 99.9% of their food from photosynthesis, and that alone. I have 2 large derasa and a smaller squamosa in my 66 gallon and they do nothing noticeable to the nutrient levels.

    Just a follow up question: I know derasa clams are supposed to be the "easiest" to keep, but what makes them the easiest and are maxima or squimosa clams THAT much more difficult to keep?

    It is my experience that Derasa are more forgiving when it comes to higher nutrients to the system, and less then ideal water chemistry (to a point).
    Maxima and Crocea to best under the most intense lighting once acclimated to that lighting, and Derasa, Squamosa, and Hippos will thrive lower in the tank.

    Perfect that's exactly what I was looking for.

    I use a combo of led (sb reef lights) and t5 (one biotek marine t5 led and one ATI blue+ traditional t5 bulb). My PAR reading at the sand bed of my tank is around 80-100. Which clam would do best with that par value?

    Probably Derasa, and Hippos.

    I would start with a Derasa and if the clams does ok then try a Squamosa. Both can be fast growers so take that into account regarding tank size and utilization of elements. My Hippos sucks up the Ca like a sponge.
