- You are adding inline filtration because your current setup is clogging up emitters and causing uneven reservoir output.
- You are switching to a higher-capacity system because your current pre-filter chokes under peak irrigation demand.
- The heavy-duty mounting bracket is worth its weight in gold when you are tight on floor space in the pump room.
- The shut-off valve is a simple addition that saves a massive headache during those routine filter swaps.
- Users who added this ahead of their RO unit say they doubled the life of their main membranes.
- Reservoir managers say they stopped seeing sediment buildup in their irrigation lines after installing this.
HydroLogic TALLboy Dechlorinator & Sediment System
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. The HydroLogic TALLboy Dechlorinator & Sediment System is built to handle that full range, reducing up to 99% of chlorine while filtering out sediment, rust, and silt. It utilizes a high-capacity 5 micron sediment filter to ensure clean water before it reaches your plants.
Beyond basic dechlorination, the TALLboy also reduces 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 and a 7,500-gallon filter life, making it well suited as a high-capacity pre-filter ahead of a Stealth-RO300 unit or as standalone inline treatment.
Built for low-maintenance reliability, the TALLboy 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. For smaller operations, the HydroLogic smallBoy offers a more compact alternative for dechlorination.
