Benefits & Features

Automatic pH Maintenance

Know with confidence that your plants are safe from harmful pH swings. No more daily pH checks or chemical additions, you can take ease in knowing your pH is balanced in the perfect range for great harvests.

Less Reservoir Changes

By ionically balancing the system, not only is pH stabilized but the ionic health of the reservoir is better maintained and balanced. This safely allows for less frequent reservoir changes, saving time, labor, water and nutrients.

Greater Nutrient Efficiency

By targeting and eliminating pH swings at their root cause (charged hydrogen-ions that build up in the system over time), your plants have greater ease and ability to access nutrients as they need.


Reusable, Sustainable

• Recharges for repeated uses, with a simple rinse in Torus Hydro pH Regulator Recharge Solution.

• Cost-efficient recharging lets many growers save money compared to pH up/down chemicals.

• Multiple uses per unit, multiple recharges per bottle. Designed for sustainability, for growers' budget, and a healthy planet.

• Recharge every 2-4 months, or use a larger model for your system and recharge even less often.

How Does It Work?

Using ion technology, the Torus Hydro pH Regulator attracts and captures the charged particles that influence pH, targeting pH problems at their source and keeping pH in the ideal range for proper growth.

PH is a measurement of charged-hydrogen concentration, and as this concentration changes growers then see spikes or drops in their pH value. What growers are actually witnessing is an excess of positive (H+) or negative (OH-) hydrogen ions building up, which then inhibit the plants from properly absorbing the nutrients they need. Without the Torus Hydro pH Regulator, this then requires growers to keep constant attention to make sure that the pH is maintained in the proper range.

The charts below represent a recirculating hydroponic system, where the plants themselves alter this hydrogen ion-concentration by releasing hydrogen ions into the water/nutrient mixture as they grow:

Excess H+/OH- ions build up in the system during photosynthesis, causing pH fluctuation, blocking nutrients from proper absorption, weakening the plants’ immune systems and diminishing yields.

ion chart w pph

With the Torus Hydro pH Regulator, excess H+/OH- ions are attracted and captured from the system, creating a balanced pH, a healthy reservoir environment, and greater nutrient-use efficiency, resulting in healthy plants and great harvests.

The Torus Hydro pH Regulator acts as an outlet for these ions, capturing ions that would otherwise raise or lower pH outside of the ideal range. Simply drop the Torus Hydro pH Regulator capsule model into your reservoir or connect the Torus Hydro pH Regulator Inline Edition to your pump, no power required.

What Growers Around The World Say

Since 2017 Torus Hydro has been delivering solutions to make hydroponics easier, simpler, and more sustainable for growers across the globe. Today the Torus Hydro pH Regulator has users in the US, UK, Canada, Australia, New Zealand, Spain, France, Germany, Sweden, Russia, Switzerland, Singapore, Chile, and more. See what growers around the world have to say:

I’ve really loved using the Torus so far!… The Torus Hydro device is doing exactly what [it] advertises and keeping the pH of the res super stable – I definitely recommend!

I did enjoy the PH Torus Hydro pH and it worked for my Veg RDWC …[I used it] for four solid runs !

It worked very well. 35gal Gallon original PH Torus Hydro pH Stick. These are the bomb ! …it’s truly the savior to water culture.

Working well on all systems f&d [Flood & Drain], nft [Nutrient Film Technique], dwc [Deep Water Culture].

(Torus Hydro pH) Works great.. Kept pH between 5.8 and 6.3 for over 8 weeks until I was finished!

One of the Best and Smartest inventions made for Hydro and water stabilization for Ph. King approved!

This thing basically maintains proper pH levels in hydroponics for optimal plant growth for you on autopilot. Pretty legit.

I’m using the 35gal…and my pH is from 5.8-6.2

Since I set my pH it’s been working.

Everyone should be using these, absolute game changer!

[We] LOVE our new pH management device called Torus Hydro pH. NO MORE CHEMICALS in my water to buffer pH! This device is so awesome and ez to use.
