Brightwell KoralColor??

[freezetyle]

with most of the supplements like that you probably won't notice any difference unless you are at an Ultra low nutrient level.



EDIT:

Just saw your other thread. Biopellets are really efficient at sucking out the other stuff. You could defiantly try it to see if it would help. I might also suggest an amino acid supp as well.
Maybe give the bright well stuff a try. If it helps with coloration, i would think about switching to the zeo line, more expensive initially but the majority of the supplements are two drop twice a week.
