I have an old reef that is 10+ years old. I removed the lights many years ago so it's mostly down to a bunch of very nice live rock, sand and a few mushroom polyps, sponges etc. Anything that can survive low light. I'm thinking about adding light and again growing acros and such. The tank that the light will be over will be a 29 gallon tall. I have a huge sump and other tanks on the system for about 200 gallons total. It has been awhile since I have done any research on reef lighting and it seems things have changed a bit. Any suggestions? LED?
