UPDATE:
Well I got back last night from christmas holidays expecting algae all over my glass, and to who knows what. I told the person taking care of my tank to not bother cleaning the glass (I am withholding his name to protect his innocence
)
Well, I come home and to my surprise, not much algae at all to clean off the glass. Corals look great, actually I think even better. Wife even commented on how good it looked. The tank only had its second dose of the goods.
Color looks slightly better, but more importantly some corals that were quite brown or dark greenish, are now showing signs of color improvements.
So far I am impressed!
