[duds]

I am getting a 70 watt mh halide retro for my 29 gallon tank and was wondering if this would be enough lighting for a crocea clam?

It would be ok if you choice a bulb with prety good PAR. I would look into getting 10K.

 

[mbbuna]

10k for sure. 150's put out more PAR then 175's, but either one would be better the the 70w

 

[duds]

wait so which one is better 150 or 175

Clams come from shallow areas,. so 10K would simulate their lighthing better. I think since 175W is more common, the price could be lower than 150W as well.
