DaveDe Posted October 3, 2012 Share Posted October 3, 2012 cheap hydrometers aren't worth much. Maybe I'm wrong - but I'm only four weeks in and it's giving me readings that I don't believe are accurate, plus they fluctuate if I tap it (and no bubbles are floating off). So am I doing it wrong or was my first mistake buying the cheapest thing available? In the beginning my tank was around 1.023, now I'm seeing it rise to 1.026-1.027. I've only been adding fresh RO water due to loss via evaporation so it shouldn't be going up. Oh wait, other factors. Think I'll reread that section. Link to comment
patback Posted October 3, 2012 Share Posted October 3, 2012 Justgo to Bulkreefsupply.com and pick up a refractometer for 40 bucks. They're so much better and easier to work with. Link to comment
DaveDe Posted October 3, 2012 Author Share Posted October 3, 2012 Yay, that's the answer. I didn't want to give the spouse a heart attack when I bought the start up gear initially and so......but I figure there's some other folks who can relate. Link to comment
Nano sapiens Posted October 3, 2012 Share Posted October 3, 2012 Did you buy a 'swing-arm' type? Link to comment

Haelstrom Posted October 3, 2012 Share Posted October 3, 2012 I picked up this one. Cheap and works great. Link to comment
Swanwillow Posted October 4, 2012 Share Posted October 4, 2012 I've never had good luck with swing arm hydrometers. I did use the glass bob up and down ones with luck for a long, long time... But now I got a refractometer. VERY worth it Link to comment
