Does White work on increasing the whiteness of your CRS in your point of view? Does it work for you?
"White" is not a magic solution that you drop in the tank and all of the sudden your shrimp turn snow white. If you want white shrimp then first and foremost you need good genetics. Not sure where you got your shrimp but many people sell their culls so these might never get ideally white. Getting the white to come out is a combination of genetics, temperature, water parameters, food and even light. I use the white supplement but I also have everything else in check...I'd post it here but it's Saturday night and I'm getting ready to hit up the bars.
