Soothing Shrimp Posted October 28, 2014 Report Share Posted October 28, 2014 Interesting. Since I have had my ph meter set up and running continuously, I noticed that as the temperature goes higher, the ph goes lower. (I have very little kh in my crystal tank.) I just checked online to find out if this is indeed the case, and it appears so: "The most basic chemical reaction affecting pH is the dissociation of water:H2O --> H+ + OH-Over the temperature range 0 to 60 degrees Celsius [32F - 140F] , this reaction becomes more favorable. This means that neutral water will contain a higher concentration of H+ as the temperature increases, so the pH will decrease.

OMG Aquatics Posted October 28, 2014 Report Share Posted October 28, 2014 Interesting. I noticed my guppy tank has a PH of 6.8-7.0 Straight from the tap is 7.6 PH Shrimp tanks with no heater are 7.6 PH. Quote Link to comment Share on other sites More sharing options...

rostick555 Posted October 28, 2014 Report Share Posted October 28, 2014 Interesting find. I have noticed a correlation between temp and TDS in my tanks. I have not done research on it but find that my Sulawesi tanks have a tds range of 240-280 and my non heated tanks range from 160-180. Sorry for going off topic just thought I would add my observation on this as well Soothing Shrimp 1 Quote Link to comment Share on other sites More sharing options...
