Regular Member scaring Posted August 24, 2008 Regular Member Share Posted August 24, 2008 I had to do a major water change on the big tank and put Elvis in the 12g while I did. I tested the tap and found to my dismay that the PH (which had been running at 8.2 and 8.0 for the past few months, since I got my test kit) suddenly is registering at 7.4. Now what. I read that a rapid PH change could cause a PH sickness. With Elvis already so sick, the last thing he needs is to get sick from a PH change. How can I safely move him from a tank w/8.0 to a tank of 7.4? What is PH sickness and what should I watch for? 0 Quote Link to comment Share on other sites More sharing options...
