Does the refractometer give the same reading as the hydrometer? If the refractometer(RM) doesnt, then theres something wrong with it. Could be that its defective or the calibration fluid is no good. Try testing other SW other than yours. _________ 9YR OLD 90G/55g custom sump/refug Mag18 Aquac 180skimmer 692w MH AC jr,yel&kole tang,midas&convict blenny,B&G chromies,Blk/yel fin chromie blackcap,nemo,neon goby,6line; Blastomussa Merleti,Acan ,BUBBLE,Torch,LTA, Acropora(2) Moon, assort zoas, yel& G star polyps, P&B ricordia, montiporas, cup&candy corals, xenias,B/G mush,flower ane(2), cherry red mussa, dusters,cleaning crew..
