I know...I have a problem. I was organizing my supply cabinet and realized I have clearly accumulated more test kits than should ever be necessary. BUT it has been helpful having everything I need at arms reach, and the ease of use of these kits has caused me to test consistently, which I’m...
My new refractometer from BRS came in, so I calibrated it and checked my S.G. OMG!!! I thought I had things under control because I have a friend with a refractometer which I checked against my hydrometer. It showed that my Hmeter was off a bit so I was able to compensate for it based on his...
We are taking pre-orders for the new tester. It features graphite sensors for in tank use and better reliability. We expect orders to begin shipping next week.

So, I got tired of looking at my record high salinity readings on apex (due to error in calibration) and decided to get it properly calibrated and put it in use...
I purchased a pinpoint calibration solution and waited eagerly for it to arrive. I have "hopefully" calibrated the probe the right...
I've been building up my equipment for this 90 gallon reef tank I'm currently putting together, and the one thing i am not clear on is the refractometer. I say that because they all look the same, while some are substantially more expensive than others. Are there major differences in quality and...
So after watching the video and finding that my local store had some in stock, I decided to pull the plug and grab one.
I have an issue with the reading I am getting.
I have three different refractometers that I have collected over the years.
All three have been calibrated using standard...
Are you properly calibrating your refractometer?
Lot of people just use RO/DI water which will read 0..however your not going to get the the most accurate results.
the next batch of people will use proper 35ppt/1.026 calibration solution which gets you closer.. but ar you taking into account...
I have been getting asked a lot of question form new reefers on what all is involved in maintaining a saltwater reef tank. Yesterday i decided to film my "weekly" routine of maintenance to give a good overview of what all is involved in maintaining a reef tank.
Below are my general weekly...
I got my refractometer from BRS the other day and noticed that it's blue line doesn't seem straight across. For example, I have it perfectly set at 35 ppm on the right side, but my salinity on the left reads like 1.027 or 26. It seems to me like the reading (if set at 35 ppm) should be straight...
Hi,
I had a floating saltwater gadge witch is inaccurate and has claimed the lives of two clownfish and a shrimp because it gave an inaccurate reading and caused a salinity spike during a water change. I am looking to buy a more accurate, quality refractometer but need help picking one. I am...
Hi all, I was wondering what you thought about the inexpensive (usually "ATO" branded) salinity refractometers as far as accuracy, do they last very long, etc.
I have a feeling at $19 shipped with a case, they're pretty popular!
Thanks!
I just opened up my new refractometer and out of the box it's saying my RO/DI water has 0ppt / 1.0 SG and my tank has 1.027 SG. Should I even bother trying to calibrate this? Some of the Amazon reviews state they took it straight to the LFS to test and theirs were already calibrated...

Aquarium Salinity: How to Measure and Why It's Important
Salinity is one of the most important parameters measured in reef aquaria. It controls not only the salt balance between an organism and its surrounding environment, but also the levels of a host of ions in seawater that aquarists neither measure nor control independently. Consequently...
