So when I used to live with my grandfather, water changes were simple (aside from carrying buckets up 3 flights of stairs lol) his faucet water's pH reading was always a steady 7.0. I moved out two years ago and my faucet water is like 8.0 (we live in the same city, a small 3 mile town). So I wonder what causes fluctuations in pH from house to house? My dad however lives in a new apartment building, his pH was always perfect, recently has been reading about 7.6, went back to my grandfathers (very old house but modernized) his is still 7.0. Could it be weather affecting build up in the pipelines? If so why does it affect some and not all? I now use alkaline buffer with my water changes to keep it stable for my SA/CA cichlids. Any suggestions? (And I've tested water, let it sit in a cup 24 hours retest & stayed the same 8.0)
