The tank is an older model with the corner partition filter box.I am adding a 175w 10k and vho actinic setup this week.Very basic but has served me very well and corals have been growing like weeds.I only do water changes and add no supliments.Fish consist of blennies,gobies and clowns.Also have softies,lps and sps...as well as one bubbletip anemone.System is almost 3 years old.
