The PerfectpH Inline Edition 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

    I bought this after buying their original version. They both worked, but the inline seems to be performing better with my setup. It was a major problem before purchasing this. It’s pretty big, so take note of that. I don’t know what else to say, it works. This will help If you don’t want to sweat your pH all the time. I’m happy I can spend some of my time doing something other than babysitting my reservoir all the time.
