Clams par level

[musel101]

What par level does everybody keep their Sand bed at at a heavily dominated clam tank? I keep mine at 350 par.

That sounds like a good par for clams. I have a few, can't recall the par they are getting but iff I recall correctly it was 3-5 hundred where they are perched on a shelf. I just added a 1/2" Deresa that the LFS had for $20. I saw the clams on the way out and couldn't resist one at that price. Reminded me of the good old days, but I'm rambling. Let's see what others toast their under.

Hard to pass up a deal like that!

Can I assume that is the reason my Maxima is turning from blue to purple edged?

They can change color for a few reasons including age. Do you know what par its under? Typically for maxima, crocea, 300 would be minimum par.

Never had one before. (3 months now) Its about 3 inches long. Approx four inches off the bottom of a 17 inch deep tank. Radian Led 68% intensity. No idea of the par. Accor's doing well at the top

This explains everything to me why I had a hard time keeping maxima clams. The last two I had I placed on my sand bed. I just recently purchased a PAR meter and measured at my sand bed measured at 100 Par.

Clams look different from side view to top view. Looking from the top the colors are quite more vibrant.

I have measured the PAR now with my light intensity at now 70% intensity
390 PAR just under the water line, 200 PAR in the middle, and 85 PAR at the bottom
The PAR was 87 just above the clam and now its 123 PAR
I lowed my light down by approx. 6 inches. By lowing the light this increased the PAR. The light is now 8 inches above the water line.
I have 390 PAR at the top just under the water line, in the middle 200 and just above the clam 123 PAR the bottom is 85 PAR.
I understand that LPS do well with 75 to 150 PAR. SPS do well at 200 and 350.
So the calm may still need to be risen to the 200 PAR level.
