Refratometer - My 2 cents worth
 
I have been using one of those plastic rectangle testors for years and relying on it.

The other day I broke down and bought a proper refractometer.

To my amazment my old testor was reading very low LOTS

When I tested it with my old my reading was 1.0025

New meter 1.0030:cry:

I suggest to anyone useing one of the cheep testors go out and get a good one.

yeah very good idea to start with one the hydrometers are very unreliable i also found they read 4 points low but if you allow for that your good lol

I was shocked at my reading.

Remember to change your salinity level slowly now too

Did you type that right? 1.0030 is actually really low. Most people target 1.025.

But if that was a typo then yeah I'm not surprised. I've heard this story a lot... hydrometers being out by .005 seems to be pretty common.

And you certainly can't assume they are always out in the same direction or even always out the same amount each and every time. Heck a few micro bubbles on that arm and it can act up.

Refractometer is king!

i see no real dif in those besides the fact that the vertex is way cheaper.

ALBERTA REEF 02-07-2010 05:15 AM

Thats what I thought. I was leaning more to the vertex side and the info sells it better.
