![]() I did a water topoff yesterday and tests today with my new refract. and got 1.029 and then a test with a hydrometer it was on 1.024 Wow a big difference (temp of tank was 80.1F)
I can't remember the formula to correct the hydrometer results vs temp to confirm the refractometer is correct anyone help on the results?
