Dull Coral Color, Decent Parameters. Help?

[kkgaskin90]

*DULL* Color... Can't edit title :/

75g mixed reef + 20g sump. Coral Box D700. Carbon dosing. Battling Hair Algae. Corals have been losing color for about 2 weeks now and I can't figure it out. Nothing has changed. Any ideas?

How are you measuring phosphate?
Since the nutrients are seemingly low, corals may need more nutrition.

I might let the N and P (pending how it is being measured) rise a bit, or dose something like amino acids.

I'm using Salifert test kits

Agreed 100% with Randy
No3 and po4 may be lacking
