  • It takes more than 5 drops of the phenol red.
Size: Refill Solutions
The OTO works great with 5 drops, but not so much with the phenol red. If you have the normal 5 drops per test kit that many of us use, this is not the same. The color is very difficult to see with only 5 drops of the phenol red in testing the Ph. It takes 10 drops to get the same amount of color, or you have to half the amount of water that you are testing. 5 drops will work, but it's very difficult to see. ... show more
