Generally the pH will stay in the range of 5.7-6.5, though most systems will balance between ~5.8-6.2

An improper pH is a symptom of an imbalanced charge environment around your plants' roots.

The balanced pH environment the PerfectpH creates is actually a secondary effect of the perfectpH removing the excess charged H+/OH- ions that build up in the system as the plants photosynthesize over time, allowing the nutrients to be in their most accessible form for the plants.

The ideal pH for a hydroponics system is a frequently debated topic and there are many misconceptions regarding it. A hydroponics system may show a reading that a grower may consider an ideal range, by use of chemical buffers or buffer injection systems, but unless the plant’s roots have an outlet to release the excess charged ions that build up, a grower will always be fighting the pH from changing. In addition, this charged ion buildup inhibits nutrients from being bio-available (in their most accessible form) to the plant’s roots for uptake.

Different nutrients are taken up by the plants at different pH levels, so a 100% fixed pH reading isn’t exactly an ideal environment either. Rather than a fixed number, the pH moves slightly within a limited range, as different nutrients are being absorbed at their ideal pH level.

​​The perfectpH significantly reduces water and nutrient consumption by reducing the need for reservoir changes.

By the perfectpH allowing the solution to be free of excess H+ ion build up, the plants can absorb the nutrients in the solution with significantly more efficiency. This leads to less wasted nutrients building up in the solution, meaning the reservoir’s environment stays in a healthy state for longer periods of time. Less reservoir changes are then required in a system using the perfectpH, and thus water consumption is significantly reduced.

Understanding how the perfectpH does this first requires an understanding of why reservoir changes are necessary. A reservoir change, removing the water and nutrient mixture from the solution and replacing it with fresh water and nutrients, is required frequently in a typical hydroponics system that isn’t using perfectpH.

As a plants’ nutrient requirements change, or as their life cycle progresses, nutrients that are being blocked from absorption are unable to be used by the plants and build up in the solution.

This is why growers may see a high PPM reading, typically thought to indicate a high level of nutrients available in the solution, but the plants do not appear healthy.

As these unused nutrients build up in the reservoir they actually inhibit freshly added nutrients from being absorbed as effectively by the plants. This is why a solution would typically need to be flushed on a regular basis.

Based on a bi-weekly reservoir change schedule, water consumption can be reduced by up to 200-300% annually using the perfectpH.

If the temperature of the reservoir is too high this could interfere with the device working to it's full capacity, and could potentially result in a pH reading a full pH point higher than the ideal range. Lowering the temperature of the reservoir can resolve this issue. An easy method a user can test this with is to freeze a couple water bottles into ice and drop them into the system to see if it has any effect, or if using a chiller a user can turn the setting to a cooler temperature. We recommend the reservoir temperature typically be in the range of 65-72 F (18-23 C).

If the reservoir temperature is within the recommended range and you are still experiencing a high pH, and using rockwool/clay media that has not been treated, proper pre-treatment of the media may resolve this issue.

Although many people consider clay or hydroton media to be relatively inert, it can cause pH rise due to its basic or alkaline nature, which will buffer the system upwards. This effect can be magnified with clay or hydroton that has been sitting for long periods of time. The solution to counteract this upward buffering is the following:

Leave the hydroton/clay in a solution of 1 part vinegar, 2 parts water for over 48 hours. Rinse with water thoroughly to remove any remaining vinegar and return the media to the system.

For larger systems where removing the media may be less feasible, we recommend to run a pH 3-4.5 buffer over the media within the system for several days, adding additional buffers if the pH drifts. When the pH becomes stable the solution is ready, and the media will no longer interfere with the perfectpH’s ability to most effectively regulate the system’s pH. Common buffers that could be used include the following: phosphoric acid/hydrogen phosphate and acetate/acetic acid.

Water circulation is an important factor when using the PerfectpH. It is recommended to run a higher flow pump when using the PerfectpH than may be typical for your system's specifications. Make sure the pump is free of debris and has a significant flow rate, as a low flow rate can cause the PerfectpH to not function as effectively.

Though there is not currently a set recommended schedule, if using a flood-and-drain system or system where the pump is not running continuously, it is recommend to run your system with relatively frequent flood/pump cycles. It is important that there is significant circulation for the PerfectpH to work properly. It is generally recommended to run the pump for a 15 min duration every 2 hours while grow lights are on, though this may be dependent on specific system variables.

If the flood schedule is infrequent and cannot be adjusted, an additional pump and/or larger PerfectpH model can be used to supplement this infrequency.

Alternatively, the PerfectpH Inline Edition, can help ionize the water/nutrient mixture more effectively for systems with less frequent flooding schedules or smaller diameter tubing. Please see the PerfectpH Inline Edition User Guide for more info.

The PerfectpH is recommended for Deep Water Culture (DWC), Nutrient Film Technique (NFT), Flood and Drain, Aeroponics, or any combinations of these techniques. The PerfectpH is not recommended for Aquaponics Systems.

For Drain to Waste (Run to Waste) systems, the PerfectpH Inline Edition is recommended, and will require a “Pre-treatment tank” or “Holding tank” to ionize the water/nutrient mixture prior to sending it to the garden. Please see the PerfectpH Inline Edition User Guide for more info.

Use of un-stabilized silica as an additive can cause the perfectpH to work less effectively, or cause the pH to increase. When using silica with the perfectpH it is recommended to use a brand that is pre-stabilized, such as OSA28, and dose as recommended by manufacturer.

Oxidizing agents such as Hydrogen Peroxide or other oxidants used for sterilization are not recommended for use with the perfectpH.

Some non-chelated organic fertilizer nutrient mixes may be less effective with the perfectpH, dependent on the specifics and environment of each system.

For best results it is recommend to use the device in systems with plants with developed roots, as this allows the perfectpH to work most effectively with the ionic environment.

The PerfectpH Inline Edition will not require roots to be present, as the forced flow through the unit will allow the ion exchange to be more effective than the standard model.

When not in reservoir or in water, store the perfectpH in it’s included capsule, with cap(s) firmly sealed.

Store at temperatures not exceeding 122 F / 50 C.

In order to keep your perfectpH natural ion pH balancer working optimally, it is recommended to periodically remove the perfectpH from the reservoir and submerge in the Torus Hydro perfectpH Recharge Solution. This releases the build up of OH-/H+ ions and toxicities that the perfectpH has captured from your system.

Reservoir changes are recommended every 4-6 weeks for the current model perfectpH, or when the pH rises outside of the optimal range typical for the crop being grown.

It can be noted that in our testing, recommended reservoir change cycles have been exceeded by several weeks with no apparent detriment to the plants, though the pH may show to be higher than is typically considered acceptable.

This depends on the size of your reservoir, the number of plants in your system, and the model of perfectpH you are using.

For example, the 35gal perfectpH typically will work optimally in a 35 gallon reservoir for 2-3 months before needing a regeneration, depending on number of plants and root mass, as more plants and a larger root mass will lessen the time before regeneration is required. A 70gal perfectpH could be used in a 35 gallon reservoir, increasing the time needed before regeneration to 4-6 months. Inversely, a 35gal perfectpH could be used in a 70 gallon reservoir, but would require more frequent regeneration, approximately 1-1.5 months.

Yes, this is normal. The perfectpH should be kept in a moist environment at all times, even during storage. Because of this, changes in climate or temperature will cause slight condensation to form on the inside of the container capsule. This is normal and does not affect proper functioning.

If the composite inside your perfectpH has become dry, it will rehydrate when submerged again in water, though it may require a recharge to return it to full optimal efficiency.

Yes, the perfectpH ships internationally and we have built relationships with select distributors around the world, and are actively building more.

Sometimes after a fresh "Recharge", some of the acidity from the Recharge Solution can get trapped inside the perfectpH and this may lower your system pH slightly for a bit of time. This is why we recommend to rinse thoroughly after each Recharge.

Secondly, upon the first use, the perfectpH will release some acidity as the ions begin to balance the system. We usually recommend adding a bit of pH up after the first 24-48 hours to counteract this initial drop. After this, the system will stabilize to the ideal range. This is only required on the first initial use, and will not be required thereafter.

In order to keep your PerfectpH natural ion pH balancer working optimally, it is recommended that after 2-3 months of use, to remove the product from your reservoir and submerge it in the PerfectpH Recharge Solution. This releases the build up of H+/OH- ions that the PerfectpH captures from your system.
