Review: Replacement - Replacement for Red Phenol from BioguardTM test kit. Cheaper and just as efficient. Because the solution does not seem to have as much colorant into it, I simply use half the water in the test tubes, but the results are identical. Otherwise the color would be the right tint, but faded.
Review: Not good balue - Weak color.

## Questions & Answers

**Q: So is this saving me from putting one drop of chlorine neutralizer in**
A: Yes! and If I may add, when you do your PH test, use about 25% to 50% the amount of sample water from your pool, or SPA, or... . Otherwise the colour is very light, correct tint .... but very very light.
