Hi everybody !
I've got not typical question (I think) well, what should I do to have
totally white sand in my tank ?
I have not the foggiest idea how people do that ;-)
What kind of animals (fish, crabs...etc) do you recommend me to put them
into the aquarium ?
more hermit crabs ? I've already added one (now I have two hermit crabs and
six fish-zebrasoma flavescens, paracanthurus hepatus, 3 a.ocellaris,
salarias fasciatus)

my tank size (76 G, 50kg live rock)
HQI 2x150 + 2x58 actinic

thanks for help
Ralph
