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 PerfectpH Recharge Solution.

• Cost efficient recharging let’s 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 PerfectpH 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 PerfectpH, 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.

With the PerfectpH, 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 PerfectpH acts as an outlet for these ions, capturing ions that would otherwise raise or lower pH outside of the ideal range. Simply drop the PerfectpH capsule model into your reservoir or connect the PerfectpH 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 PerfectpH 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:

“Been using this for 3 weeks in 3 systems and it’s working! Even I doubted, but proof is in the pH!”

“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!”

“[PerfectpH] Works great.. Kept pH between 5.8 and 6.3 for over 8 weeks until I was finished!”

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

“Everyone should be using these, absolute game changer!”

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

“I did enjoy the PH PerfectpH and it worked for my Veg RDWC …[I used it] for four solid runs !
It worked very well. 35gal Gallon original PH PerfectpH Stick. These are the bomb ! …it’s truly the savior to water culture.”

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

“You’re going to love this unit so much! Trust it, let it [run], trust what it’s doing and watch how much of a change you will see… It’s the best item I’ve tried!”

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

“So far, so good.”

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


What pH value does PerfectpH maintain?

The PerfectpH maintains pH at least within 5.7–6.3 pH, depending on the set-up/plant type/feeding/stage of growth, allowing for slight fluctuation within this range for best nutrient absorption. For most systems, the pH will be maintained between 5.8-6.2.

Does it do anything else?

Yes actually! In addition to balancing pH, PerfectpH maintains the ionic balance of your reservoir, allowing for more efficient nutrient absorption and less frequent reservoir changes. Some of our growers go full harvests just topping their reservoir up without problem. We recommend a res change around every 4 weeks for most setups.

How do I recharge it, and how often?

To recharge, remove the PerfectpH from use and submerge the capsule model in (or fill the Inline Edition model with) PerfetpH Recharge Solution liquid for about 2 hours.

Rinse the unit with water and return to use. We recommend a recharge every 2-4 months for best use, but a larger model can be used for your system to extend this time even further.

How does the maintenance cost compare to using pH up/down?

We sought with the PerfectpH to not only make pH maintenance easy but also affordable. Though the initial cost of a PerfectpH is more than buying a bottle of pH up or down, for many growers the maintenance cost in PerfectpH Recharge Solution costs less than frequently using pH up/down chemicals, for some significantly less, with much less labor required.

Why did we create PerfectpH?

Coming with several years of growing experience and a love for the art and science of hydroponics, we’re a team of growers based out of California, who became frustrated with pH problems and the time requirement of frequently checking pH and adding up/down chemicals. We felt there had to be a better way.

We sought out a way to solve this, and after several years of research and development the PerfectpH was born. We felt that there must be other growers who felt how we did too, so we decided to create Torus Hydro to provide growers around the world the freedom and ease of hydroponics without pH worries.

Can I use it in a non-recirculating system? Or a gravity-feed tank?

Yes, the PerfectpH can be used to maintain balanced pH in a reservoir tank (also known as a pre-treatment tank or holding tank), which can then be used with a drain-to-waste / drain-to-use / drip-to-waste / drip-to-use system, or can also be used for non-hydroponic soil cultivation. This tank can be used as a source to hand-water plants, or to pump-feed or gravity feed the system.

To use the PerfectpH like this, connect the PerfectpH Inline Edition to a pump and place inside the tank. This will then circulate the water/nutrient mix through the PerfectpH, treating the mixture and resulting in a balanced pH and a healthy reservoir environment. The diagram below represents this type of use:
