Hi everyone, i was wondering what device you guys are using to measure the salinity in your saltwater tank? As for my budget i'll go as far as 80 dollar. The cheapest and accuracy is better. Thanks for all the helps.
my coralife hydrometer only cost 12.00. i have been useing it for 2 1/2 yrs now
i havent had a problem. some people use the more expensive ones but they dont sell those around here so i go with what i know.
the best way is to use a refractometer. they sell for about £49.99 over here (aquamedic) these will be the most accurate. TMC make the best hydrometer but I don't think you will be able to get one over there.
