Also what brand of hydrometer do you have? I have the Coralife Deep Six that I checked against the LFS
refractometer. Although a hydrometer is not very accurate, they are consistent on their readings. In their water the refractometer read 1.024 where my hydrometer read 1.0215. So now that is what I shoot for. The guy at LFS
said most hydrometers read a little low. I would get yours checked against a refractometer. Then you know what SG
your water is without paying the price of the refractometer.
