Refractometer Help

So I got sick of using a hydrometer because I never trust its readings and decided to break down and get a hydrometer.  Bought one of the "buy it now" ones off Ebay from a respectable seller.  It's the RHS-10ATC model and had 10 star reviews, phenomenal ratings on reef sites, etc.

Look at it towards a bright light/sun if you can't see a reading I would say it's a dud. I have one that may be the same one I have it looks like it, very easy to read.

I would say it is a dud. That really sucks

That image is funny. I like it. I've felt that way myself the last few days.

Just for the record, a hydrometer that is calibrated and then kept clean by rinsing in freshwater after each use and given a periodic vinegar bath when it starts to look cloudy, is just as useful as a Refractometer. Yes, it is.

I guess the other thing that comes to my mind is that people worry too much about salinity. Between 1.022 and 1.028 is just fine so long as it does not get raised by oh, let's say .005 in less than an hour. (I'm not sure why, maybe it's the action of a big rain storm, but a fast decrease is no big deal, like when adding a lot of freshwater for topoff).

So you can stop fretting. It's okay. Don't worry. Be happy.
Glad you survived the operation. Sorry it did not help as much as you hoped. On the bright side, your tank looks good. I'd like to drop by sometime to see it in person.
