💪 Powerful Pinpoint PH Controller Interface – 120VAC for Precise pH Control Review

contains everything you need to monitor, calibrate and control two circuits to keep the pH of solutions within an acceptable range. I have used this with 2x 12v metering pumps connected to 2x 1a 12v power supplies connected to the unit. with a little optimization and dilution of the solution, it works great. Place the probe near the solutions outlet to allow the system to microdose for best results

Have been using this in my 75g freshwater planted aquarium for almost 4 years Connect a CO2 tank solenoid valve to this as CO2 will lower the pH. Personally I don't even use a diffuser, I let the air line flow to the inlet of the canister filter. As long as the bubble rate is kept at a reasonable level, the CO2 will remain in the tank long enough to fully dissipate. However, after a recent cleaning of the filter, burping occurs from time to time as the flow rate through the filter has improved…

I bought this product because my F-Zone CO2 regulator is not reliable when it comes to a stable bubble rate. After he overdosed and killed my fish, I decided I needed more protection. This PINPOINT pH controller gives me the certainty that the pH of my aquarium is well controlled. It is easy to use, looks very accurate and reliable. If I had to say a bad thing, I would say that the instructions don't explain very well what the range setting actually does, but it's easy to see that it sets how…
