SPS Experts - Explain difference between "browned out" and light brown/tan SPS color
It appears many post concerns with "browned out" sps corals....including myself. However, I have noticed a trend (in my tank and others)....the browned out corals are not the typical dark brown color you see with inadequate light or excessive nutrients....they are usually a light brown, almost tan color. So, what is the difference between brown and light brown?
This is currently troubling my tank. Some corals are especially prone to it, such as the different types of tricolors (yes, those are also prone to pests, but I have ruled those out). So whats the answer? Anyone have any experience with coloring up tan/light brown corals?
My own theory is that there is an excess of nutrients, but also an extreme excess of light, resulting in the coral having some type of inner battle...lol, who knows though - just want to get rid of the tan colors....perhaps less light, with more GFO would help...strange Idea, i know - but I am leaning this way. After all, the original GARF tanks where run only by VHO and didn't have much algae...colors were excellent.
Anyways- open to any thoughts and or discussion on this topic. What I do know is that there is a REAL difference between browned out corals and sps corals that are light brown/tan that are suffering. These days, I rarely ever see someone with a true "browned out" coral that plagued the hobby 5-10 years ago. If anything, our tanks are quite clean and light is likely more than enough...in short - Dark brown corals are easy to help, light brown though, I'm lost.
