Crystalpro Purisen 100ml - Organic Waste Filtration Resin for Crystal Clear Aquarium Water - Regenerable - Fresh and Saltwater

About this item

• CRYSTAL CLEAR WATER CLARITY – Purisen is a premium porous filtration resin specifically engineered to polish aquarium water to perfection. It rapidly absorbs organic waste, fish waste, and food residues that cause unsightly yellow discoloration, delivering professionally clear water in both freshwater and saltwater environments.
• REDUCES NITRATES & CONTROLS AL GAE – By trapping organic pollutants before they break down into toxic compounds, Purisen actively helps lower nitrate levels. This preventative filtration supports fish health, reduces stress, and limits the nutrient spikes that fuel nuisance al gae growth.
• REGENERABLE & REUSABLE – Don’t replace your filter media; renew it. Purisen acts as a chemical sponge that can be easily regenerated using a standard chlorine-bleach solution followed by a safe dechlorination and remineralization process (using Crystalpro Aqua Conditioner and salt). This reuse capability makes it a highly cost-effective, long-term solution.
• HIGH EFFICIENCY CAPACITY (100ML TREATS 400L) – A little goes a long way. Our concentrated formula is denser and more efficient than standard media, with just 100ml treating up to 400 liters (approx. 105 gallons) of aquarium water. It targets organic waste specifically, leaving essential trace elements intact for your livestock.
• INCLUDES MESH BAG FOR HIGH-FLOW FILTERS – Purisen comes pre-packed in a durable mesh bag for immediate use and easy removal. It is designed exclusively for high-flow environments such as canister filters, hang-on-backs, or internal filters to ensure maximum contact time. (Note: Not suitable for filterless setups or low-flow bowls).
