Mobile Bay Reef Keepers

After extensive testing me and Scott have come to the conclusion Hydrometers are crapola.
I have two that are 3 points off, and Scott will post how far off his is. But just to be 100 percent we tested our refractometers against each other, different brands....right on the mark.

I think Brandon had the same problem with his hydrometer when he tested his water with my refractometer. I think it was off about 3 or 4 points.

Water testing at the next meeting would be a very interesting experiment and a good opportunity for us to see if we are getting into trouble!

I had gotten John to test my water, at the meeting at his house, with his refractometer and I had the same problem with my hydrometer. A refractomer is so much easier to use and less mess. I think hydrometer are crap too.

All my hydrometers got thrown in the trash LONG ago.

Was having a lot of weird problems, found out my hydrometer was way off and salinity was 1.030. Wouldn't trade my $29 refractometer for a bucket of hydrometers.

Where do you get a refractometer for $29?

Ahh, good find Kevin! I got mine from eBay, about 35-40 shipped

Scott told me about it.

My hydrometer read 1.025. Kevin's refractometer read ABOVE 1.030.

What about a group bye?

I doubt you could much cheaper unless you mean combining shipping.

I kept mine and marked it where I wanted my SG to stay. I use it in the tank and when I start mixing water and then use the refractometer.

I need one.
