Red Sea 225 Micron Felt Fine Polish Filter Bag — 4" x 10.5" Overview Capture suspended debris and keep sump chambers cleaner with Red Sea’s 225-micron felt filter bag. The thicker felt balances efficient particle removal with stable flow, making it a great everyday mechanical pre-filter for reef and fish-only systems. Sized for standard 4-inch sock holders, swaps are quick and maintenance is simple. Key Features 225-Micron Capture – Ideal for routine mechanical filtration without excessive clogging. Durable Felt Construction – Thick, stitched seams help prevent bypass and collapse. Standard 4" Collar – Fits most sump sock brackets for fast changeouts. Optimized Length (10.5") – Good contact time while maintaining steady sump levels. Easy to Clean – Rinse and rotate; machine-washable (no detergent) to restore flow. Reef & Fish Safe – Inert materials suitable for marine and freshwater use. Product Specifications Type: Felt filter bag (mechanical pre-filtration) Micron Rating: 225 µm Size: 4" ring diameter × 10.5" length Material: Polyester felt with reinforced stitching Top Style: Rigid 4" collar (standard sock holder fit) Recommended Use: Everyday water polishing / detritus capture in sump intakes Care: Rinse after use; machine wash warm without detergent or fabric softener; air dry Replacement Cadence: Rotate/clean every 2–4 days; replace when fabric thins or seams show wear

Red Sea 100 Micron Felt Fine Polish Filter Bag — 4" x 10.5" Overview Polish your aquarium water and trap fine particulates with Red Sea’s 100-micron felt filter bag. Sized to fit standard 4-inch filter sock holders, the dense felt material captures micro-debris for crystal-clear water and smoother skimmer/biological performance. Ideal for routine water polishing in reef and fish-only systems. Key Features Fine 100-Micron Filtration – Captures small particulates, detritus, and food fines for superior clarity. Durable Felt Material – Thick, stitched construction resists collapse and maintains flow. Standard 4" Collar – Compatible with most sump sock holders for quick swaps.

Red Sea Marine Care (MCP) Nitrite & Nitrate Test Kit Overview Monitor two critical parameters with one reliable kit. Red Sea’s Marine Care (MCP) Nitrite & Nitrate Test Kit provides easy, color-based testing to track the nitrogen cycle during tank start-up and to manage nutrient levels long-term. Clear reagents, durable glass vials, and an intuitive color chart make results fast to read and repeatable—ideal for fish-only, mixed reef, and coral-heavy systems. Key Features Two-in-One Testing – Measures both nitrite (NO₂⁻) and nitrate (NO₃⁻) for complete nitrogen-cycle visibility. Reef-Friendly Resolution – Low-range sensitivity helps detect early spikes that can stress corals and inverts. Easy Color Matching – High-contrast chart and step-by-step procedure minimize guesswork. Consistent, Repeatable Results – Precise droppers and stable reagents support dependable readings over time. Great for Cycling & Maintenance – Track nitrite to confirm biological maturation; monitor nitrate to guide water changes, filtration, or carbon dosing. Quality Components – Includes glass vials with tight-sealing caps, reagent set, and printed instructions in multiple languages. Product Specifications Parameters Measured: Nitrite (NO₂⁻), Nitrate (NO₃⁻) Test Method: Colorimetric (liquid reagents with visual comparison) Intended Use: Marine aquariums (FOWLR and reef); suitable for ongoing nutrient management and initial cycling What’s Included: Reagents for NO₂⁻ and NO₃⁻, glass test vials with caps, measuring syringe/dropper, color chart, instructions Storage & Care: Keep reagents tightly closed, dry, and out of direct light; rinse vials with RO/DI after use Maintenance Tip: Use alongside routine water changes, protein skimming, refugium or media changes, and feeding adjustments to maintain target nitrate levels

Red Sea MCP Marine Care Master Test Kit Overview Get five essential saltwater tests in one box. The Red Sea MCP Marine Care Master kit measures ammonia, nitrite, nitrate, pH, and alkalinity to help you cycle new tanks, diagnose issues, and maintain stable parameters in fish-only and reef aquariums. Clear color charts, sturdy glass vials, and easy, repeatable procedures make testing fast and consistent. Key Features All-in-One Coverage – Tests NH₃/NH₄⁺ (ammonia), NO₂⁻ (nitrite), NO₃⁻ (nitrate), pH, and alkalinity (KH). Cycle & Maintenance Ready – Track start-up progress and long-term nutrient/chemistry stability. Easy-to-Read Results – High-contrast color charts and step-by-step instructions reduce guesswork. Repeatable Accuracy – Precision droppers, syringes, and glass vials support consistent readings. Reef-Safe Ranges – Designed to resolve the low ranges important for marine livestock. Cost-Effective – Multiple tests per parameter provide months of routine monitoring. Specifications Parameters: Ammonia (NH₃/NH₄⁺), Nitrite (NO₂⁻), Nitrate (NO₃⁻), pH, Alkalinity (KH) Method: Colorimetric/liquid reagents (with visual comparison); alkalinity includes titration-style steps Intended Use: Marine and reef aquariums (FOWLR, mixed reef, coral-dominant) Included: Reagents for all five tests, glass test vials with caps, syringes/droppers, color charts, instruction booklet Care & Storage: Keep reagents sealed, dry, and out of direct light; rinse vials with RO/DI water after use Maintenance Tip: Test at consistent times each week; pair with regular water changes and filtration adjustments to keep parameters in target ranges
