The TORUS PerfectPH Regulator 130L is a breakthrough cartridge that holds your nutrient solution inside the optimal 5.7 – 6.5 window, around the clock, without pH up, pH down or daily measurements. Curated by BloomLED for serious hydroponic growers, it fits any recirculating reservoir up to 130 litres. You save hours of work, your plants get steady nutrient uptake, your harvests get a lot more predictable.

No more overnight pH drift or morning spikes after feeding. The cartridge buffers continuously, so your roots take up nutrients at a steady rate — leading to faster, more uniform growth across your canopy.
Forget jugs of acid and base in the grow room. PerfectPH removes pH down and pH up completely: your water stays stable with no daily chemical intervention. Cleaner, safer, and gentler on beneficial microbes in your reservoir.
Drop the cartridge in, forget about it for 8 to 12 weeks. You save several hours of measuring and adjusting over a full cycle — time better spent training, defoliating or simply enjoying your plants.
Built for DWC, RDWC, NFT, recirculating aeroponics, drip and ebb & flow. Plays nicely with every major hydroponic line on the market (House & Garden, GHE, Canna, Hesi…) and with pH-sensitive strains that hate variations.
The heart of PerfectPH is a forced-flow ion-exchange resin, patented by TORUS HYDRO and battle-tested in professional hydroponic facilities. It releases or captures H+ ions to keep your solution exactly where roots want it: 5.7-6.5.
Just place the cartridge directly in your reservoir or inline on the recirculating loop. No power, no plumbing tweaks. For a reservoir bigger than 130 L, step up to the 260L or 380L version. For non-recirculating systems, set your starting pH manually then use the cartridge to hold the value.
Why is the target window 5.7 to 6.5?That's the pH band where most macro and micronutrients (N, P, K, Ca, Mg, Fe, B, Mn, Zn) stay maximally available to hydroponic roots. Outside that window, certain elements precipitate or lock out, which leads to deficiencies and yellowing — even when your nutrient strength is correct.
When should I replace the cartridge?Lifespan is 8 to 12 weeks depending on your water hardness, solution EC and reservoir change frequency. Very hard water (high bicarbonate content) shortens runtime. When pH starts drifting again despite the cartridge being installed, it's time to swap in a fresh PerfectPH Recharge 500 mL.
Does PerfectPH work in soil or coco?PerfectPH was designed for recirculating hydroponics (DWC, NFT, drip, RDWC). In soil or hand-watered coco the contact time with the resin is too short — stick with classic pH down here. For recirculating coco runs, however, PerfectPH performs flawlessly.
No more pH up, no more pH down, no more 10 pm measurements: the TORUS PerfectPH 130L cartridge keeps your nutrient solution dialled in for an entire cycle — the single highest-leverage upgrade for any serious hydroponic grower.
