I added some new live plants this afternoon and ever since I did my water is cloudy. I can see tiny white particles floating everywhere. Mid level to bottom there is hardly any particles but from midway to top there is so much the water looks cloudy. Everything tests fine but ph is still high (7.8). Can someone tell me what these particles are and will it just go away eventually? Is it coming from these new plants? Sadly, came home to find both my angel fish had died (only had them a week) :-(
