I was wondering if anyone had heaard of useing alum to lower the ph in a hydro system. I am setting up a dwc system and my ph was around 7 the guy that put together my system said to use alum to lower it since I had no ph down. Well I used it but know my water is very cloudy. Is this okay? The ph is right on 5.9 about perfect but the cloudy water worries me. Any input would be most helpful
