SKU: PCHO0084 Category:


The PerfectpH is a revolutionary pH stabilizer that automatically balances the pH of your hydroponics system or reservoir, keeping it in the ideal range for optimal nutrient absorption. PH maintenance is an essential factor in any hydroponics setup. Without the plants being naturally rooted in the ground, excess alkalinity builds up in the system, creating a toxic environment for the plants. The perfectpH solves this by removing the positively-charged ions that cause this build up, creating the perfect pH environment for your plants.


  • Avoid excess pH swing that inhibits plant growth and weakens the plants immune system by removing excess toxic alkalinity build ups creating a perfect environment for plants.
  • Eliminates the need for chemical buffers, frequent reservoir changes, pests, wasted water/nutrients. It also helps increase yield.
  • In recirculating systems, PerfectpH will auto balance to 5.7 – 6.5 pH.
  • In non-recirculating systems, simply set your pH and PerfectpH and will keep it within ±10% range.


  • Eliminate the need of buffers such as pH Up and down
  • No longer required to check daily pH
  • Reduce frequency of reservoir changes
  • Use less water
  • Use less nutrients
  • Less maintenance and labor required

    Before this, I was starting to shop automatic ph adjusters because it was consuming way too much of my time. I didn’t use this for quite some time after buying it. I run a drain to waste with a reservoir/water chiller combo. It helped me a lot. I kept it next to pump intake as advised. I still made some adjustments here and there until the inline version arrived. Before using any Torus products my pH was rising more than 10 points at a time. I was using pH down and always diluting my solution to keep the EC in check. It was a major commitment. This has proven to be a reasonable solution to my problems.
