My water is actually GREAT. I have well water with an EC of .09 and PPMs of less than 100. According to the lab, my water is perfect for hydroponics.
Then what is all the stuff in your reservoir ? Looks like calcium or silica to me. Is your water cloudy after mixing your nutrients and minerals?I am using Canna aqua nutrients
Not sure whose reservoir that is but it's not mine. Since switching to Jack's my reservoir is crystal clear with a slight blue tint. I got away from AN Ph Perfect products.
