Reef A

Taken as a close-up from the right side. Yesterday the return pump from the sump refused to restart after having been shut-down for feeding. Another pump had to be installed. The pump that failed was a Rio 1200. It was removed and cleaned but still would not start so a Hagen 802 powerhead was adapted to take its place. The later pump has a much lower flow rate so it may have some affect on the corals.
