Recently meet up one of the senior reefer ask him what he usually dose for his SPS and he recommand Fauna Marin Ultra Amin. It is Amino acid. It has for LPS & SPS. So i bought 1 at iwarna to try it out. Has been trying this product for a few days for my SPS, noted some changes as my SPS poly extendation is getting longer then usually. But for colour can't really see yet as i only use for a few days. Hope my SPS can colour up from this wonderful product bought in by AquaFauna Supplies. Anyone
