Bullfrog Frog @Ease Spas Bundle Classic Bullfrog Frog @Ease Spas Bundle Classic makes Bullfrog spa water care simple, consistent, and low-chlorine, so owners can focus on soaking instead of dosing. Custom-designed for Bullfrog’s dual-filter “Classic” configuration, it delivers Fresh Mineral Water® with far less work than traditional dichlor routines. Key features and benefits Uses FROG minerals plus SmartChlor® technology to maintain a steady 0.5–1.0 ppm free chlorine level, cutting chlorine use by up to 75% compared with standard systems. Self-regulating SmartChlor automatically releases more sanitizer as needed, eliminating yo‑yo chlorine levels and reducing shocking to about once per month. Provides softer-feeling, low‑odor water that is gentler on skin, swimsuits, and spa surfaces while still killing bacteria in two ways (minerals + chlorine). Low-maintenance routine: replace the SmartChlor cartridge every 3–4 weeks and the mineral cartridge every 4 months or at each drain and refill.
