The IceCap 4K Gyre Flow Pump with Controller bundles the 4K Gyre pump with IceCap’s standalone Multi-Function Controller — five flow modes, a feed timer, and an automatic night mode that drops to minimum flow when ambient light is low. No app or WiFi required.
Controller features: controller lock, 20-minute feed mode, light-sensing night mode
Mount: waterproof magnet mounts, up to 5/8in glass or acrylic
Warranty: 1-year limited
The light-sensing night mode is a nice touch — the controller automatically drops flow to its lowest setting after lights-out rather than needing a manual schedule, which better matches how fish and corals actually rest overnight.
Compatible replacement parts: propeller sets and magnet mounts for the 4K Gyre.
