The AquaFX Add-On Sediment Filter Kit 10x2 is a valuable accessory designed to enhance the pre-filtration capabilities of your existing Reverse Osmosis (RO) unit, or it can be used independently. This kit is specifically engineered to tackle heavy sediment loading in your water supply, safeguarding the finer 1-micron pre-filters within your RO system from premature clogging. This comprehensive kit includes a durable clear canister, complete with a sturdy mounting bracket, allowing for easy installation. At its core is a high-quality 20-micron washable sediment filter, offering an effective barrier against particulate matter. For convenient setup, a 5-ft length of tubing is also provided. It is recommended to monitor pressure, and the filter should be washed or replaced when a 5 PSI pressure drop is observed. This added protection is an excellent investment for any reef aquarist dealing with high levels of sediment in their source water. By installing this add-on, you can significantly extend the lifespan of your RO/DI system's more delicate filters, ultimately saving both time and money on maintenance. It ensures a consistent supply of cleaner water, which is crucial for the health and stability of a saltwater aquarium.
