? on nitrates and clams

I always read about how clams consume nitrates. My tank always had no more then 5 ppm of nitrates. Since getting my clams ( I now have 7) the nitrates register 0. Is this going to hurt them? I feed my fish pretty heavy ( 4-6 times per day) and add DT's twice a week. Should I up this?
 
Hey chicki,

don't mean to hijack your thread here.. But I've got a similar question, but on the other end of the scale.

My tank always registers nitrates at around 15. I was wondering if my tank would be adequate to house a maxima clam in terms of water quality. Lighting will be 2 x 250w MH's, along with 2x NO actinic.

I too have read that clams tend to lower nitrates, so in essence, the clam would be purifying my water, right?
 
Chicki-
You should be fine with regular feedings which add nitrates and phosphorous.

Clams are used as filters but not as a solution to a water quality problem. Find out why your nitrates are high and correct it.
I do know of a few professional systems using clam filters. These systems are stable but able to handle high bioload.
