Been lurking around this site for a while trying to learn as much as I can. My tank has been up and running for a year now. 80 gallon bow front . Going to jump into LED's. Would like the opportunity to grow some different corals. Thinking I will need two LED units for my tank. Are the Hydra 52's worth the extra money compared to the Hydra's? Don't want to kick myself in the butt a year from now wishing I had bought the 52's instead for $400 dollar difference. Any input would be appreciated.
