Coralife 100108103 First Impressions

024 and my refracto read.

I found mine was calibrated out of the box. At first, I was getting bubbles sticking to the rotating arrow. Wipe down glass surface to dry it and put it back on the shelf til next time. So once your instant ocean shows a measurement. Does just as good of a job of any meter you would buy at the store! I tried it over and over and no bubbles! Simple to use, but if there are any air bubbles the results will be way off.

Coralife 100108103 Final Thoughts

Easy instructions.

I couldn't decide between this and one of the float arm meters or both. Once I figured that out, it works great. Now its easy to make sure I have the correct amount of salt in my aquariums. I use this for my 10g brackish and it works ok. My only criticism would be that it's a little too dark. I will update later to see if the refractor will keep its calibration. The instant ocean hydrometer will always be right.
