3C Carbon Cartridge Aquastyle 620/620T

• The Aqua one 3c carbon and polymer wool cartridge
• The 3c cartridge itself is however quite a clever little thing designed with complex aims and objectives in mind.
• The carbon tray does indeed hold the carbon granules which are an essential and very purifying but can also be messy if left to roll around.
• The Aqua One 3c carbon and wool cartridges are not designed to grow the beneficial, nitrifying bacteria so often sought after by the fish keeper.
• 3c cartridges don't always last the full six weeks in between changes and it's worth checking on their performance once per week.

Product description The Aqua one 3c carbon and polymer wool cartridge is one of our best selling products for a good reason - it works exactly as it should, trapping fish waste and purifying aquarium water for 4 to 6 weeks after which it gets thrown away and replaced. What could be simpler? Aquarium Maintenance Made Easy... The 3c cartridge itself is however quite a clever little thing designed with complex aims and objectives in mind. The polymer wool top layer is carefully manufactured to be a specific thickness - dense enough to trap a month's worth of solids yet not impede water flow. The polymer layer is also carefully bonded to the carbon tray, in such a way as provide support and prevent sagging when it gets dirty. Directions Replace the cartridge every 4 to 6 weeks. If water is pooling on the surface, change the cartridge immediately. Do not attempt to wash the cartridge.
