So I've had this female C. Quad (Red-Claw Crayfish) for about two and a half months now and she has been doing great... molting regularly and growing fast, always hungry. When doing water changes I've always used tap water treated with ph regulator that put the ph at 6.5. I decided to stop using the ph regulator to save money and slowly adjust the ph of the tank to my tapwater ph (7.8). I did the first water change a couple days ago with the 7.8 water without adding the ph regulator and now she is acting a little funny. Shes constantly climbing the walls and trying to get out of the tank which she has never done before, and her appetite has decreased. She NEVER turned away food before and now shes leaving most of her pellets untouched. Should I abandon my attempt at adjusting the ph and just continue using the ph regulator?? Does she just need time to adjust to her changing environment?? What should I do??
