Aquatic Life 100gpd RO Membrane

Aquatic Life’s 100 GPD RO Membrane is a polyamide thin‑film composite (TFC) reverse osmosis membrane designed for aquarium, hydroponic, and residential water purification. It is the core filtration stage in Aquatic Life’s Classic RO/DI systems, RO Buddie units, and Twist‑In cartridges. ⭐ Key Takeaway The Aquatic Life 100 GPD membrane produces up to 100 gallons/day of purified water and typically removes 95–98% of total dissolved solids (TDS) when operated at proper pressure and temperature. 🧬 Membrane Type & Function Material: Polyamide Thin Film Composite (TFC) membrane Filtration precision: Reduces contaminants down to 1/10,000 of a micron Targets: Heavy metals (arsenic, lead, copper), salts, dissolved solids, parasitic cysts, and other impurities This membrane works by forcing water through a semi‑permeable film under pressure, separating purified permeate from waste concentrate. 📈 Performance Specs Rated capacity: 100 GPD (≈4+ gallons/hour at 65 PSI & 77°F) Typical rejection: 95–98% TDS Minimum pressure: ~30–35 PSI (booster pump recommended below ~40 PSI) Ideal pressure: 65 PSI Operating temperature: 39–100°F (optimal 77°F) pH tolerance: Continuous 2–11 Free chlorine tolerance: <0.1 ppm (carbon prefilter required) 📦 Physical Characteristics Standard RO membrane size: ~11.75" length Fits: Aquatic Life Classic, RO Buddie, Twist‑In systems, and most standard RO housings 🔧 Lifespan & Replacement Typical life: 1–2 years with proper prefiltration and flushing Replace when: Rejection drops below ~95% Product water TDS rises above 5% of feed TDS 💧 Waste Ratio Most systems produce 1 gallon purified : 3–3.5 gallons waste, depending on pressure and flow restrictor design. Booster pumps improve efficiency. 🐠 Why It’s Good for Reef Tanks Produces low‑TDS water ideal for mixing saltwater Protects sensitive livestock by removing metals and contaminants Works seamlessly with DI resin for ultra‑pure output
