It has been specifically designed to control the pH in mixing tanks for fertilization. The small and precise flow of the peristaltic pump allows you to maintain ideal pH values in your tank. After selecting the desired pH setting from 5.5 to 9.5 pH, the pH controller measures the pH value of the solution and automatically adds pH adjustment (acid or alkaline) to change the liquid’s pH to the selected level.

Works well, o issues, 2 months now, very happy, hoping it has a long life. This unit keeps the PH within 2 or 3 points in 30 gallons.

I have had this for a little over a year (it's only had a few months of use off and on) and the motor on the doser burnt out. I contacted warranty support using the number on their website and they sent me a replacement without much of a fuss and were a pleasure to deal with.

If you have a reservoir that needs constant monitoring and adjusting then you absolutely NEED this. It took awhile to get the sensor and dosing tube positioned properly so as not to overdose (this system does a single does until your set PH level is reached) but once we dialed that in it has worked flawlessly. We added a wave maker to our reservoir on one side where the dosing tube is and placed the sensor on the opposite side so the PH solution mixes quickly and doesn’t overdose. We also diluted our PH Down solution 50/50 with distilled water to make it even less likely to overdose. All in all a great piece of equipment if you take the time to dial it all in.

Worked great in my deep water culture system to regulate pH, bought an industrial pH meter though so it lasts longer! Still working good!

Came broken right out of the box. Garbage product with terrible build quality and quality control. Heard something rattling around inside so I opened up the plastic green box and found a blue resistor laying inside. Then I realized that the circuit board isn't even attached to anything. It's just lazily slapped inside and there is nothing holding it down so it can flop around.DO NOT BUY THIS PRODUCT. Save yourself the headache of having to return this pile of trash and buy the more expensive Blue Lab doser. Blue Lab stuff does not break. I tried to save money on a PH doser because I have to buy a bunch of these for my needs. glad I only bought 1 to test before I bought more. I will be buying Blue L:ab from now on.

It overdoses by an insane amount, I came home to find my water at 3.2 when set at over double that. The doser pump seems to be decent, and the sensor is accurate but the actual communication between sensor and doser is terrible, it should only turn on for 5 seconds, turn off, check pH, turn on for another 5, check pH, until it reaches the desired level. If you're thinking about purchasing this I highly recommend you spend a bit more on the BlueLab pH doser.

I have been using this setup for over a year. it keeps my pH perfect. The negative reviews must be from people just setting up and hoping for the best. This isn't a 'smart meter' it's just a pH probe and a dosing pump with set variables in the controller. The fewer gallons you treat, the weaker your pH solution needs to be. If you treat a gallon, then one pump from this doser and your pH will sky rocket in the set direction. I treat about 50 gallons with mine using GH up and down solutions with no issues. I regularly double check with a hand held probe as well to make sure this probe is staying accurate! Also you have to keep your probe clean, calibrated, and wet in order for it to function properly. This product is more than worth buying at this price when put up against the competitions' prices. I normally don't leave reviews on products but was about to buy another one of these setups and noticed the negative reviews. I just thought I'd set things straight!
