Yes, I would recommend this.

Not so good

Pros: Cute bottle that you can reuse.

Cons: Doesn’t do the job.

Purchased from MD east coast warehouse. The Hana pen and another calibration fluid agree at 35 ppt. This one reads 41 ppt. I floated the bottle to make sure the temperature was 77 degrees. It’s $5 in the trash. Not worth spending the time to call customer service to get a refund. I use a ton of brightwell products. Makes me wonder if they are a good company.

Add this to your monthly calibration list

Pros: Accurate to 35pct 1.026 specific gravity

Cons: Little leakage from the tip while shaking.

This solution is fantastic and helped me recalibrate my refractometer (I was off by 3% salinity) and now I am going to use this to recalibrate me refractometer every month with my other probes and testers.

Wrong Salinity #

Pros: None

Cons: It should be 1.026....... but its at 1.029

I have a 120g mix reef tank. I have been losing LPS and could not figure out why. I ordered an ICP test. It showed my tank at 1.029. My calibrated refractometer shows 1.026. I calibrated it with water and got a new one. It shows my tank at 1.029!

The solution was defective and I just trusted it..... This should NEVER happen.
