It is bulbs replacement day on my EZ550reef!
Replacment of the 6x T5 bulbs should have been done long ago.
4x were 9.5 months old
2x were 14 months old
I saw the colors of the corals on the bottom slowly deteriorate for a few months. This process had been going on for more than 3 months. In accordance with the requirement to replace the lamps every 6 months at SPS corals.
happy DSR reefer
