The Tub Outlet Screen is an essential component for any tray-based hydroponic system, designed to act as a primary physical filter at the point of drainage. By pressing securely into your Tub Outlet or Tub Outlet Extension, these screens create a robust barrier that prevents large particles—such as expanded clay pebbles (hydroton), perlite, or loose root mass—from entering the return lines. This simple yet critical addition safeguards your plumbing from the frustrating blockages that can lead to reservoir overflows and uneven nutrient distribution, ensuring your ebb and flow system operates at peak efficiency.\u003c\/p\u003e\n  \n  \u003chr\u003e\n  \n  \u003cp\u003e\u003cstrong\u003eBest For:\u003c\/strong\u003e Clog prevention in Ebb \u0026amp; Flow (Flood and Drain) trays, reservoir intake protection, and managing debris in high-flow drainage systems.\u003c\/p\u003e\n  \n  \u003ch3\u003eKey Features\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eIndustrial-Grade Filtration:\u003c\/strong\u003e Features a high-flow screen pattern that allows nutrient solution to drain rapidly while effectively trapping medium-sized substrate and organic debris.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePerfect Friction-Fit:\u003c\/strong\u003e Engineered for a precise, tool-free installation.
