AQ-4020 Aquarium RO Water Filter System
The AQ-4020 two-stage reverse osmosis filter is an entry-level RO system suitable for smaller freshwater, marine and reef aquariums. Perfect for nano-reefs! The granular activated carbon pre-filter removes chlorine as well as organic contaminants. The thin film composite (TFC) reverse osmosis membrane removes algae promoting phosphate and nitrate and other contaminants. Your aquarium will be cleaner and require less maintenance with reverse osmosis water. The AQ-4020 is compact and easily fits in tight spaces, allowing for easy installation. The quick connect hose fitting makes it easy to hook up the filter when you need to make water, and then store the filter system when you are finished. Replacement activated carbon pre-filters and TFC reverse osmosis membranes are available.
