I believe @907_Reefer posted a small sps tank over grown sps tank with explosive coralline algae growth, absolutely stunning.
You may be talking about our previous tank from ~2013, if so, thanks
The live rock back then was just fantastic, we ran this 55g (HOB filtration) under 8, 4' T5s half blues half whites. Tank was less than 2 years old here, we sold it off when we moved up to Alaska.
