Help me get some color back!

[blennymower]

I have a couple of sps that have had color fade away. They have a lot of polyp extension and are showing signs of growth.

Here some quick info:

Cal 480-500
alk ~11
mag 1400-1500
pH 7.7-7.9
temp 79-82

Light: actinics(200w) 10hrs .......MH(500w) 8hrs

Changed bulbs from 10K to 14K

Macro/micro algae and sponges are growing and plentiful so I'm sure nitrate and phosphate are near zero if tested (cant confirm)

What do you think? What can i do to get some color back?

ph is a little low, but more importantly I think you should use some sort of a bacteria driven product. I'm personally looking into Zeo Neo myself, its an alternative to vodka dosing and according to some does wonders for your color.

How about some specifics? What SPS specifically? Pics? What do you mean by "faded"? Just pale? Brown?
