Hey Honkit,
i am currently on sugar + bacteria in a bottle . . . But i am slowly absorbing from some reefers and would one day like to go for vodka+vinegar. . . .
No sand .... handful of rocks.... so majority of the tank is spS on glass
Only some rocks are in the tank to create some place to paste my frags. . . . majority of the rocks white and ugly (revive from dead rocks) are in the sump
