is this what I need?

I am E bay hunting today and still use a hydrometer so I decided to look into replacing it with this:


Best Deal Salinity Salt Refractometer 4 Aquarium Hydrometer Softcase | eBay

any thoughs?

 

pretty much the same one i have although mines blue. ive had mine for 5 years and it still works great. Time for you to ditch the hydrometer for sure!!

 

lol thats wha I thought lol is ther anything special that I need to do once I order it?

 

Im a big fan of the BRS refractometer comes with a nice case and calibration fluid udner $50

 

Definitely get some calibration fluid.
Then see how far off your hydrometer was!!

 

just looked at the one BRS carries and it literally looks identical LOL

 

and BRS is out of stock grrrr....

 

I did just that after 6 months of a hydrometer and believe it or not they read the exact same!! ALthough I did clean with vinegar once a week or so.

 

I have had my hydrometer for 3 years, havent cleaned it but the good news is that I can get teh fluid off BRS for about 10 bucks shipped and the refractometer off E-bay so that save me 6 buck plus shipping if I went through BRS.

and I will definatly post to see the diffrence between the two.

 

aqlright so I went with BRS deal made more sense at the time, SO let this be a lesson my swing arm read 1.024 a bit low but about right.

the new mwter after being calibrated and tested three times read 1.028 a bit high.

then I got to thinking about when I first got the tank up and running and the cal. mag read high at 1.026 salinity by the swing arm. LOL will spend 100+ on water test kits but 10 bucks to measure the salinity
