Just started this tank Dec 1, 2016. Tank was given to me from a friend. Seaclone filter, modded aqueon whisper, stock coralife light, given heater. Used only RODI to start. 30lbs live sand, 40+lbs dry rock. Added handful of snails and hermit crabs Jan 3. Added 1 emerald crab and 2 snowflake (?) clowns yesterday, Jan 13. Been testing with my refractometer, API tests (fresh and reef).
