Hi Jose and
to TR.
3. Will this be your first tank? Nano tanks are more difficult to keep stable than larger tanks and can crash fast. You will need to be very careful to maintain excellent water quality. Are you planning on a
sump?
4. I recommend
live rock (LR) and live sand (LS) for filtration. You can also go
LR and bare bottom. I'd start out with 15-20 lbs of
LR.
Before you set the tank up I'd leak test it with fresh water. Once you are sure it is not leaking empty the tank. Add the sand to the bottom of the tank and then put a big sheet of plastic or a garbage bag over it. Fill your tank 2/3 of the way with saltwater that has been made from
RO/DI water (or, in Puerto Rico maybe
NSW), carefully remove the plastic and then add your
LR. Carefully pour the rest of the water in, trying to not disturb the sand. You may want to drop a raw table shrimp into the tank for a couple of days to help jump start the.
