Exploration of the flow phase diagram more fully reveals the dependence of deposition/ablation frequency on system parameters. The color bar in Fig. references the frequency of clog ablation at different conditions, with the color map shown on a log scale. As C Ca 2+ increases at a constant C Alg , moving vertically upward in the diagram, the frequency of ablation increases proportionally. Fig. shows this increase at three different constant values of C Alg , while Fig. (b) provides the details for C Alg = 0.1 mg/mL. Furthermore, increasing calcium at a fixed C Alg essentially increases the crosslink density. Thus we summarize this effect as f ∼ n, where n is crosslink density. Holding C Ca 2+ constant, however, and increasing C Alg , has little to no effect on f : Fig. shows that color does not change significantly along horizontal lines until approaching the clogging boundary. Experimental conditions in Fig. obtained along a line of slope 1, where C Ca 2+ ∼ C Alg , correspond to constant crosslink density n. Increasing both C Ca 2+ and C Alg simultaneously increases C Gel , leading to an increase in f . Fig. shows that this increase can be described by f ∼ C 2
