i dont live in america so no walmart. alright so basically what does that ph thing u mentioned do i did try and research but i dont get it. does it actually change the ph or give you a reading?
The ph controller is like a timer, but instead of using time, it uses ph levels. It's used to keep the ph within a certain parameters, the ph hits the lower parameter it turns on, the ph hits the upper parameter it turns the CO2 off. I personally used it for a while myself, but no longer do. I don't like the extra maintenance of cleaning the probe as well as calibrating. And the probes don't always last forever, I had a couple go bad on me to where I could no longer calibrate, so had to get new probes. A timer is much easier, I have the CO2 turn on at lights on, and turn off at lights off. And for the bubble counter, I have mine set at around 1.5 bubbles per second. This is a good starting point, and you can always adjust up or down to reach your target ph levels, which is your target CO2 level.
The pH controller will control the solenoid, so that your co2 doesn't drop the pH in the tank below your set level.
ok what i dont get is once the ph levels get bad the thing turns off the co2. wouldnt it take 2 -3 days for the ph to lower?
Nope. pH can drop dramatically, or insignificantly, but that depends on how much co2 is being put into the water. Many sites have a chart with a relationship between KH and pH. By measuring the two throughout the day, you can see how much co2 is dissolved in your water.
The pH controller cuts the co2 to prevent the pH from dropping too low, which can lead to many deaths in the tank. First from extremely low pH values, and second from overdoses of CO2, restricting the O2 in the tank.amehel0;981836;981836 said:
