Seachem CupriSorb 4L — Commercial Bulk Copper & Metal Removal Resin for Large Aquariums & Facilities
Seachem CupriSorb 4L (SKU: 724983-209) is a bulk container of synthetic metal-extracting resin designed for large aquatic systems, maintenance companies, commercial hatcheries, and public aquariums. Large aquatic setups often encounter heavy metal risks from industrial water supplies, metallic plumbing fittings, or legacy copper medications. CupriSorb 4L is a large mini-bucket-sized pack that provides a high-volume solution to absorb heavy metals and make water safe for delicate species, thus making CupriSorb a safe aquarium additive for fish, invertebrates, and plants.
Formulated with high binding affinity, CupriSorb extracts all copper variants, including copper sulphate, chelated copper formulations, and natural mineral leachates. It operates without stripping essential calcium, magnesium, or carbon-based buffer systems, keeping water parameters stable during treatment. It can be regenerated for repeated use, making it a cost-effective and reliable solution for long-term copper control.
Usage & Application
When to Use
-
Public & Commercial Aquariums: Essential for large marine display maintenance, coral farming operations, and wholesale fish facilities.
-
Large-Scale System Restoration: Clears widespread copper contamination across connected central filtration systems.
- Particularly useful after copper-based medication treatments or in situations where copper contamination must be eliminated to protect sensitive species.
Placement & Flow Guide
-
Fill large-capacity mesh bags or fluidising media reactors and place them in the central filtration sump where the water flow is high.
-
Ensure constant water movement through the media bed to maximise copper adsorption rates.
- Monitor copper levels in water regularly and replace or regenerate when exhausted.
Product Specifications & Highlights
Key Features
-
Commercial Economy: 4-Liter volume offers the lowest cost per litre for large-scale application.
-
Reversible Acid Regeneration: Can be regenerated multiple times in dilute hydrochloric acid to extend media lifespan, thus making it usable for multiple reuse cycles.
-
Targeted Heavy Metal Removal: Removes copper(both ionic and chelated copper ions) and other heavy metal toxins such as zinc, nickel, and iron. It works while preserving macro-minerals of aquarium water, thus making it safe for sensitive water species, including invertebrates.
-
Visual Indication: Colour changes from light amber to dark black as copper saturation reaches maximum capacity.
