Which of the following is a sign that a tank mix may be incompatible?

• A. Flakes forming in the tank
• B. Clouding of the mixture
• C. Severe separation
• D. Crystals precipitating in the tank

Answer: (A)

Incompatibility between tank-mixed products shows up as unstable mixtures, and flakes forming in the tank are a clear, observable sign of that instability. When insoluble material precipitates or agglomerates, it breaks into flaky particles that can clog filters and nozzles and mess with even coverage. That visible change tells you the components aren’t staying compatible in the tank, so you should stop and reassess the mix. Other signs like clouding, severe separation, or crystals precipitating can also indicate incompatibility, but the appearance of flakes provides a direct, tangible cue that solids are coming out of solution and the mix isn’t safe to use as-is.
