Clean water in.
Biofilm out.
Biofilm builds in your reservoirs and lines for weeks before a COA catches it. FERTox is a water-treatment system that uses chlorine dioxide (ClO₂) to clear biofilm and waterborne pathogens from your irrigation lines continuously—so the root zone stays clean and the plants thrive.
Water Systems
Calibrated to your water
Measured, not estimated.
A CLEANTheory technician tests your water's demand and dials in the dose to your biofilm, mineral scale, and competing inputs—no guessing at a number off a label. FERTox injects at one choke point in the main line and runs continuously, holding a steady residual through the reservoir, lines, and emitters.
Single-point injection
See the difference
Two years of biofilm.
Gone in 30 minutes.
This grower fought the same tank for two years—multiple chemistries, power-spraying, none of it held. One 30-minute treatment with the FERTox system and its PATHox water disinfectant cleared it down to the wall.
What it delivers
Treat the water, protect the root zone.
Dosed to keep the treated-water residual below 0.8 ppm—under the EPA's maximum for drinking water—using EPA-registered chlorine dioxide chemistry (EPA Reg. No. 73139-1). It holds a steady residual, so biofilm never gets a foothold.
Addresses biofilm system-wide
ClO₂ penetrates the biofilm matrix where chlorine bleach (HOCl) and hydrogen peroxide (H₂O₂) only skim the surface—clearing the slime that clogs emitters and harbors disease.
Knocks down waterborne pathogens
Hits pathogens before they colonize lines or reach the root zone—helping hold down pythium, phytophthora, fusarium, and other root-zone threats.
Cleaner lines, fewer clogs
Uniform flow, less maintenance, and longer equipment life—with no more confined-space tank work, acid flushes, or chlorine shocks.
Better uptake, sharper crop steering
Clean lines carry your feed, not biofilm; clean emitters deliver the same shot to every plant—so your dial-in stays precise and repeatable.

FERTox — common questions.
Is it safe for my plants and my team?
Yes. FERTox is dosed to keep the residual below 0.8 ppm—lower than the EPA's limit for drinking water—so it's safe for plants, people, and equipment.
How is it different from bleach, peroxide, or peracetic acid?
Chlorine bleach works through hypochlorous acid (HOCl), and hydrogen peroxide (H₂O₂) is a surface oxidant—both get consumed by organic load. Peracetic acid (PAA) acts fast but fades within minutes. Chlorine dioxide (ClO₂) is selective and persistent: it penetrates the biofilm matrix and holds a low, steady residual across pH 2.5–10.
Do you install and service it, or is that on us?
We design the install, put it in at a single injection point, then monitor and service it on a schedule. You run your facility—we keep the system dialed in.
Can I see it work before switching?
Yes. Many growers start with a free on-site tank cleanout—a one-time demonstration that clears one reservoir of biofilm and scale so you see the chemistry firsthand. It's a low-risk way to see results first.
What does getting started look like?
- Assessment. We assess your facility's water demand and your irrigation and fertigation systems and processes, on-site or by call, at no cost.
- Prescription. Once we know your average daily water use and water demand, we prescribe the chemistry your system needs in 30- or 60-day increments.
- Installation. Installed around your grow cycle, with your staff trained and chemistry generated on site in our truck at every delivery.
- Ongoing management. On a set schedule every 30–60 days, we return to refill chemistry, handle service and maintenance, and recalibrate dosing.
