SPS color question

[michika]

Your flow sounds fine! My 24g cube ran with the exact same stuff for flow, and I never had colour problems with my SPS.

I found this on RC years ago, and thought that it explained SPS color perfectly.

"there are only two things which affect sps coloration. These are zooxanthellae density and accessory pigments.
Accessory pigments are determined by growth, light intensity and spectrum.
growth is also determined by calcium availability, alkalinity, trace elements, flow, temperature, salinity, food and stability. zooxanthellae density is relative to nutrients, growth, temperature and light intensity, spectrum and duration.

when corals exhibit fast growth, the growing margin has fewer zooxanthellae and more accessory pigments leading to colorful tips or rims.
Zooxanthellae can mask colorful pigments when they are in high densities. In nutrient poor conditions and under high light intensity and ideal spectrum, zooxanthellae populations will be further reduced leading to more visible accessory pigments especially within the body of the colony."

hmmmm.
what brand of 14k 250 de are you using?

Full tank shot.

I just fed some live BS thanks Niel, and picked up two new pieces Thanks Cprowler.

That is the cutest little clam!

The photos make it hard to tell, but are the two browned out pieces in the shade of your plumbing? Have you tried moving them around a bit, maybe to the right of where they are now?

If you want to reduce the zooxanthellae density you could try Zeospur2. It doesn't require the full system and works exceptionally well. I've used and seen instant results in hours, but you must be careful and follow instructions closely.
