I have a dottyback in my 10 gal
QT, I'm treating it for ich. I'musing the hyposalinity treatment. I'm using a refractometer, I've got the sg
down to 1.009. I need to do a water change soon, maybe 1-2 gal
. Does any one know the grams of salt to water ratio to get 1.009? I'm using Red Sea Coral Pro Salt, 33g/L=1.021. The math is getting me all confused.
