- You are adding a pre-filter to your reverse osmosis unit because your incoming water quality causes premature clogging of expensive membranes.
- You are treating water for irrigation because sediment and chemical impurities interfere with your nutrient balance and emitter performance.
- The heavy-duty bracket prevents the housing from sagging, which is a common failure point on cheaper inline filters.
- The integrated shut-off valve is a massive time-saver when you need to swap the filter without draining your entire line.
- Gardeners who installed this ahead of their systems report that they spend half as much time replacing clogged drip emitters.
- Users who switch to this setup say their nutrient solutions are more stable because they eliminated trace contaminants first.
HydroLogic TALLboy Dechlorinator & Sediment System w/ KDF85 Catalytic Carbon Filter
Municipal water often carries more than just chlorine — sediment, rust, silt, and trace contaminants like VOCs, mercury, and lead can all work their way into a grow's water supply. While the standard TALLboy system is excellent for basic filtration, this HydroLogic TALLboy Dechlorinator & Sediment System uses KDF85 catalytic carbon filtration to handle a broader range, reducing up to 99% of chlorine while filtering out sediment and heavy metals in the same pass.
Beyond basic dechlorination, the KDF85 catalytic carbon media helps the TALLboy reduce volatile organic compounds (VOCs), mercury, lead, and PCBs — protecting beneficial microbes in the root zone and reducing wear on pumps, emitters, and irrigation equipment downstream. It's rated for a 120 GPH (2 GPM) flow rate, making it well suited as a high-capacity pre-filter ahead of a Stealth-RO150 unit or as standalone inline treatment. For smaller operations, the smallBoy KDF85 offers similar protection, while commercial gardens might look to the BIGboy KDF85 system for higher volume requirements.
Built for low-maintenance reliability, the TALLboy KDF85 ships ready for quick hook-up with a heavy-duty wall-mountable bracket and an in-line shut-off valve included, so it's a straightforward plug-and-play addition to reservoir filling or inline water treatment setups where broader contaminant reduction matters most.

Frequently Asked Questions
What makes the KDF85 version different from the
standard TALLboy?
This version uses KDF85 catalytic carbon filtration media, which targets a broader range of contaminants including chlorine, VOCs, mercury, lead, and PCBs, while keeping the same 120 GPH flow rate and footprint.
What contaminants does the KDF85 media remove?
KDF85 catalytic carbon reduces up to 99% of chlorine along with sediment, rust, silt, VOCs, mercury, lead, and PCBs commonly found in municipal water.
Can I use this as a pre-filter for my RO system?
Yes — the 120 GPH flow rate makes it a great high-capacity pre-filter for HydroLogic Stealth-RO300 units, helping protect the RO membrane from sediment, chlorine, and other contaminants.
How long does the filter last before replacement?
This system is rated for 7,500 gallons of filter life, and HydroLogic recommends replacing the housings every 3 years for consistent performance.
How is this system installed?
It comes with everything needed for quick hook-up, including a heavy-duty wall-mountable metal bracket and an in-line shut-off valve for plug-and-play setup.
Does this system help protect downstream irrigation equipment?
Yes — by reducing chlorine, sediment, and a wider range of trace contaminants via KDF85 media, this system helps minimize wear and scaling on pumps, emitters, and other downstream equipment.
