Hydrometer

[htfn]

Actually I never clean my hydrometer before and I Guess I have to do that. My hydrometer effect temperature. I've been using IO since I've started and only change the salt 3,4 times. Every time I make new saltwater my reading is 1.024 but in my tank it's always 1.025. New water is 77 degrees and tank water is between 77 and 78. I have ATO, so not evaporate always same water level. I never figure out but I never think serous. I can maybe borrow one from my friend or just buy new one to compare.
