clams are fliter feeders with one entrance and one exit

ok. i have heard from some the 384watt would work for a clam in a 55 and would be well enough to keep it happy then some say no?
would it work or not?

the amount of watts or watts per gal doesnt mean anything. what you need to look at is the light delivery method and the distance the light has to travel. this is way MH lighting is superior for high light demanding organisms. look at a 250w MH bulb. all the light energy is generated and fires out of an area of about 3/4 of an inch. being fired out with that much intensity allows the photons to penetrate much deeper in the water. fluorescent bulbs have the light spread out across the whole length of the bulb so the photons dont fire out nearly as fast and cant penetrate as deep.

clams can sustain themselves through photosynthesis alone as long as they have nitrogen and phosphorus in the water to feed there zoox. this is for clams of any size, even the very tiny ones can generate enough food through photosynthesis to live and grow just fine, providing they have strong light.

clams can and will eat all sorts of plant and animal matter. it has been shown that clams will filter things between the size of 2microns and 200microns but seem retain matter in the size range of 2microns to 50microns best.

i have had mine under a 10,000k coralife white bulb and a t12 blue bulb for a month. and hes doing great... so are you sure they have to have that much light?

I would have to agree that clam looks pretty stressed and doesn't look long for this world........
JMHO!

I have the same question as well, I've had few maxima clams before, I put them on a rock near the sandbed, around a foot under water with a 150W 20k MH. they never really happy about the light, I got many different answers, some said they dont like 20k, some said my light too weak, some said it is too strong, never figured out why they are not happy >.<

what size tank? 250w will most likely be fine.

water quality plays a big role as well. its not just about the lighting.

Tank is a 36 gallon, bowfront. Water quality is perfect with the exception of nitrates creeping up now and then, despite 20% weekly water changes. (Clam will sit directly below MH fixture, approx 17" down.) Light is either 14,000 150w or 14,000 250w.

Alright, I just ordered the 250 watt fixture. I figured 150 watt would have been sufficient, but I dont want to bother having to upgrade yet again... also, a maxima clam is probably the most light hungry of all of them, and I wouldnt imagine will have a problem with a bit more light. Hope this lighting doesnt bleach my coralline...

actually i think the crocea is, but i think its max size is 6" instead of the maxima which is i think 16"

i dont think youll have a problem as long as you acclimate it to your lighting... make sure you do a proper acclimation for the clam into your tank and light acclimate it... if you had a qt tank ready for it with MH lighting that would be awesome, but if not, try to inspect the clam to check if it has anything thats bad, like pyramid snails. i have my crocea under 250w MH light and it just loves the light. it sits up high in my tank too
im not a light expert but i dont think you would be able to do that, correct me if im wrong anyone.
