Glass Hydrometer (Am I Old School)

[alton]

Glass Hydrometers, am I old school or just old? My first tank in 1980 I used a glass hydrometer, so that’s what I am comfortable with. Starting out in the ninety’s I read about refractometers that where not calibrated correctly and people having issues so I did not change. Then I tried the swing arm style, but found out after a year they became liars. Then I found one from Tropic Marin, bought it from Louis at Elegant Reef. It is very similar to the original one I had and ten times better than the glass ones most stores sell.
I have had it forever I am guessing longer than five years not over ten. I realized I needed a backup or maybe a replacement for my old hydrometer. After many visits to different stores coming up empty, I ran into the Tropic Marin rep at Macna and he sent two to Terry at Saltyfish Aquariums directly passing up the distributor (since they refused to carry it). Even though it is old, it turns out there is nothing wrong. There is a slight difference between all three but since it is only a .001 to .002 from three hydrometers I feel I am safe, especially since I normally just get it close and go. I was amazed and will send a question why my old one is highlighted from 22 to 25 and the new one highlights 25 to 27?

Is the bottom of your tank made of slate too?

Just kidding Alton. That's actually really neat. I didn't even know about the old school glass versions. Thanks for sharing!

I did have a few stainless steel frame tanks? I did think I was hot stuff when I moved up from a 5 to fifteen gallon tank

That's awesome!

It seems 35 ppt = 1.0264, not 1.025 as in the ole days. And why the old hydrometer had 1.025 as the highest number versus the new which starts at 1.025 to 1.027
