    While reading up today I came across the following written by Julian Sprung and I quote.

    "That tridacnid clams can be used to remove ammonia and nitrate from the water is well known(itt, et al 1993, Knop 1996) and this fact has promoted the notion that they could be used as a means of limiting the accumulation of nitrate in recirculating aquarium systems. Since clams are included in aquariums as ornamental features, and since thay are expensive and sometimes delicate, they are unlikely to be used in sufficient numbers to be relied on as filtration for an aquarium.

    However, some species attain large size (T.gigas, T. derasa, T. squamosa) and a large speciman of any of these may have a signaficant impact on water chemistry in a small to moderately sized aquarium. The loss or removal of a large clam in a moderately sized aquarium commonly is followed by a marked increase in the growth of algae (pers.obs) indicatng that trindacnid clams can indeed compete for the same nutrients and limit algal growth. Although interest in use of clams as filters has focused primarily on oheir capacity to remove ammonia and nitrate from water, they may also be lowering the levels of phosphate and dissolved organic material, both of which are plant nutrients."

    These beautiful creatures are really under estimated. They only do good. They are like angels of reef tanks

    Hi all - Alan did not see this thread, as he was absent for a while. Perhaps he will see it now, since I am updating it ;-)

    I have 2 clams, and would still LOVE more. BUT in different coloring - been difficult to get hold of clams for a while (that's affordable, that is ;-)

    Can you keep a Clam in a Nano like the JBJ 24G?

    The guy at the LFS told me sure with a big smile. What say you?

    Hi LappiesReef - IF you can supply the correct water parameters, and keep everything stable, as well as supply the correct lighting - then WHY NOT?

    BUT - please read my first statement AGAIN ;-)

    O.K O.K, mabe not yet, but I'll start saving in the mean time :)

    These Nano's have 4 T5's. If I place it up on the rock work would that be enough light?

    Clams make great filters. Under the right conditions they also grow huge and suck calcium and alkalinity out of your water.
