I've used the same Seatest hydrometer for 14 years. I just rinse it out with hot water once in

That's what happened to me. Found my old Seatest and compared it to my new Coralife....EEEK!

LOL! That's what I mean! I don't want to know! I run 3 skimmerless tanks
too. Just weekly water changes and the same hydrometer.
