Know before you buy
This system is specifically engineered to remove chlorine and sediment from your water supply. The combination of KDF85 and Catalytic Carbon media ensures effective dechlorination, which is essential for protecting beneficial microbes in hydroponic and organic gardening setups.
The filter is rated for a capacity of 6,000 gallons. Depending on your water quality and usage volume, you should monitor your water flow and chlorine levels to determine when performance begins to drop, as there is no built-in indicator.
The Hydrologic Small Boy is designed specifically for gardening and hydroponic applications. It is not certified for potable drinking water use, so it should be kept separate from your household drinking water supply.
No, the filter cartridges are not reusable. Once the 6,000-gallon capacity is reached or the media is exhausted, the cartridge must be replaced with a new one to maintain filtration effectiveness.
The unit is designed for straightforward integration into a standard water line. Because it is a standalone system, it is relatively easy to plumb into your garden hose or irrigation setup without complex tools.
