Okay so today is day 3 of my lowing of the salinity for my tank. I have a hydrometer that is 8inches and I just borrowed my cousins and his is also 8inches. Well not a big suprise but both hydrometers read differently. Mine read 1.013 while his read 1.012. Althought .001 isn't much in a tank that has normal salinity I've read that for hypo it must be precisely 1.009. Well, after I found out the difference, I placed an order for a refractometer and it won't be here until late next week. Is it safe for me to leave it at 1.012-1.013? I'm a bit worried that my fish will die due to the ich because at 1.012-1.013 hypo won't kill the parasites??? What are the chances of my fish dying? My fish is getting a bit thin and hasnt eaten in 3 days. Will leaving it around my SG
be helpful enough to get it to eat again or should I try to move it down to 1.010-1.011 just to be on the safer side?
Well thanks in advance!
