im just starting out with keeping sps, so i started with a small frag of acropora from my lfs, it was brown because they had it in a mainly fish system!!! but they were conviced it would come back to full colour. i brought for about £10 thought it was worth a go, since i have had it in my tank ive started to see it slightly change to green on the top of the coral, i was just wondering if it could come back to full colour??? my parameters are, salinity 35ppt, cal 450ppm, alk 8.5dkh mag 1350 nitrates at 0.25 and not sure on phosphste!!! any help cheers!!!!
