Glad they are doing well. How far, roughly, are the clams from the bulbs?

I believe moliken has in the past posted that clams need a boost in the blue light area. I can't recall what wavelength, though.

I think I may have to move the clam up on top of one of my arches, where it will look a little funny, but definitely get enough light.
I may also spotlight the clam with the PAR38 leds. From what I've read, my particular "bulb" will generate 500-600 par at 14", and 250-300 par at 20". I wonder how much par is ideal for maxima clams?

I have a couple Giesemann Pure Actinic bulbs, that peak at 421nm. Maybe they'll suffice, if I drop the fixture a bit.
