Regal 200INT Protein Skimmer

The Reef Octopus Regal 200-INT Protein Skimmer is rated for aquariums up to 400 gallons and runs a VarioS-4S variable-speed DC pump for tunable air and water flow. Five energy-saving power settings, a detachable controller with safety float switch input, and dual 15/60-minute feed-pause modes give it the same refined control as the Elite Series in the Regal's hybrid conical body. Capacity: up to 400 gallons Pump: VarioS-4S variable-speed pinwheel pump, 24V, 5 power settings Control features: float switch input, 15/60-minute feed-pause modes, 0-10V third-party controller input Body: solid cast acrylic, hybrid conical shape, fully disassembles for cleaning The 0-10V input means a system controller like a Neptune Apex can take over pump speed entirely — useful for automating skim rate around feeding schedules or bioload changes without manual adjustment. Compatible replacement parts: VarioS-4S pump kits sized for the Regal 200 series.
