Brightwell Aquatics Purit – Chemical Filtration Media – 250 mL

Quickly restore crystal-clear water with this premium filtration media that selectively removes a wide range of dissolved organics—including phosphates, silicates, and toxins—without leaching minerals. A must-have for “ugly” stages and emergency clarity. 🧪💧

What It Does

• Recommended dosage: 10–20 mL per 50 US gal for problem cleaning
• Replace every 4 weeks, or sooner if water clarity returns to low levels
