The Mantis 3 Stage RO 100 System is a heavy-duty water purification setup designed to strip out the impurities that cause mysterious tank crashes and nuisance algae. Capable of producing up to 380 liters (100 gallons) of pure water per day, it establishes a pristine baseline for marine, planted, or shrimp tanks where water chemistry is critical.

  • Stage 1: 5-Micron Sediment Pre-Filter. The first line of defense. This mechanical filter traps physical particulate matter, rust, and colloidal debris so they don't clog up the fragile RO membrane downstream.

  • Stage 2: 5-Micron Carbon Block. The chemical barrier. Specially formulated carbon strips out tap water chlorine, chloramines, and volatile organic compounds (VOCs) that are highly toxic to fish and corals.

  • Stage 3: 100 GPD RO Membrane. The heavy lifter. This Thin Film Composite membrane rejects over 98% of inorganic salts, heavy metals, bacteria, and almost all high molecular weight organics.

Setup is designed to be plug-and-play without requiring permanent plumbing modifications to your home. If you live in an area with notoriously poor tap water or chloramines, you might eventually consider upgrading to a 4-stage system (which adds a Deionization resin stage), but for most hobbyists, this 3-stage powerhouse is exactly what you need to establish a pristine baseline.
