yea, Owning a 14G biocube, the Acros probably will die. I'd try maybe an easier SPS first like a monti cap and see how that does. Honestly if you want SPS in the biocube I'd look at upgrading the lights. nanotuners has some upgrades that will fit in the stock hood. Also, along with the stock lights, the stock pump isnt that strong, only 106GPH, acros need strong intermitant flow, so i''d look into adding another powerhead or seriously upgrading the one in there. The stock biocubes are PERFECT for soft coral tanks in my opinion
