What a great product. Usually takes me 10 - 15 minutes to run my Red Sea calcium test. This thing cut it down to 5 minutes easy. Maybe less. I didn't time it. But what a time save.
Same thing with my AquaForest magnesium test. Cut the time by more than half.
And its awesome how the color changes happen so rapidly and clearly. Great product.
Saved my sump from skimmate overflow!!
I was skeptical at first by this because my skimmer is the Octo 110SSS and the cup is a narrow diameter. But when I needed it to work it did great! Something made my skimmer go crazy and it started to skim wet and overflowed into the cup.
Turned the skimmer off immediately.
Saved my sump from an overload of skimmate.
