My Xenias where nice and blooming and today in the morning when the lights came on they did not open . So I turned on my pumps that i use during feeding time and one of them wanted to but did not ..... i did a parameter check and it looks like PH is way low . So i drove to my local pet shop and got a KH test kit and my water is at 9KH . HELP ! by my research i know my KH must be from 9 to 12 and my PH from 8.0 TO 8.3 so what do i do ?
