Okay, what should it be?
My blues usually in the 90% range (LEDS) and whites, 60%. UV 90%.
Top of the water, over 350-400 par. Mid, 250. Sand, less than a 100 in some spots.
I have 4 old Hydra 52's, bought used. No idea how old they are. I sent the serial numbers to Aqua Illumination, they said they couldn't determine the age of the lights. I thought that was odd.
I don't do SPS, only LPS, softies, clams.
Everything seems okay, hope I didn't open a can of worms. But in some spots on the sand, the par reading were in the 60's.
