Most Accurate Hydrometer???

[KenyanSandBoa]

Has anyone found that one brand of hydrometer is more accurate?

I'm wondering if anyone has tested one against a refractometer...I have three hydrometers that I use to get an average reading. I know they obviously vary based on temperature and what not, but has anyone found their favorite??

I have found that my Instant Ocean reads high, my Red Sea reads low, and my Coralife reads in between the two. I tend to use the coralife reading because it is in the middle, but what if it is off???

What have you guys found??

I found that most hydrometers are off either way depending on what mood you are in while holding it.

I like refracts for accurate readings. They can be calibrated on the spot to double check. You can't beat that.

Hydrometers are junk! Just pay the 49.00 bucks and buy a Refractometer. This is the one I bought it is easy to calibrate and on the spot accurate! It is on sale for 44.00. My old hydro was off .003 that is enough to wipe out your tank because I keep my SPG at 1.025 because I keep SPS coral. Hope this helps.

Yeah, I'm thinking I'll pick up the refractometer...hydrometers do indeed suck.
