I ve been told that the "Bali Green Slimer" (Acro) is relatively hardy for an Acro...Its gonna be first my Acro attempt, I'm running 2X32 watts of PC on an 8 gallon tall. So far I have excellent polyp extension after about 10 days with the orange and green Monti Digi's I picked up last weekend, the SPS is kept about 6 inches below the light, in high flow.
