Hallo to all members... not my first tank took a break and after almost two years the itch for salt became unbearable.. so now starting out again. Have the innovative marine nuvo 16tank. Looking to stock slowly but first need to seed some rock to get it alive. Live in mosselbay so looking for a cup of sand from a mature tank please. Also thinking about using natural sea sand as substrate. I will collect below waterline for clean unpolluted sand.
