Glass or Plastic Hydrometers?

[cav]

Oh all right. Sorry if that came off wrong.

And for those that have glass hydrometers, do I just let it float and see where the water line is?

Float it straight into your garbage can and get a refractometer ha ha

The hydrometer seems to be .002 off as expected. It'll do me good until I can afford a refractometer.

How can that refractometer not use batteries? Does anybody have this one? How is it? If you guys like it I will probably get one. It worth it when you are spending $65 on polyps etc.

It's not electronic. Just like the name implies it refracts light. You put a drop of water on it and hold it up to the light. When you look in you'll see a blue area which you compare to the scale on the side.

Ya I just read that on the site lol. I guess I didnt put two and two together thanks. I just ordered it. If its a Drs Best on the site it isnt bad.

You can get one from my LFS that takes batteries as it has a built in LED so you dont need to find natural light all the time
