should i pull them out?

Just wanted to make an update. I have found what i think has been causing my ICH problems. When i started out doing SW i had a refractometer....but i broke it. And at the time i was hard up for cash so i bought a hydrometer for the mean time...no big deal right? well i hadn't replaced it until last night where i checked my DT and read a salinity of 1.030!! i went back to my LFS to make sure it was calibrated properly and used their's as a reference. it was bang on so i know now that hydrometers are a huge mistake and seems that now with my salinity slowly returning to normal everyone is looking alot less stressed! No loss either so far and i think the worst is over.
