I tested the solution prepared with the ph 7 tab, and found it high in phosphate. Water alone was free of phosphate. Now i know why I have cloudy water and an algae problem. I've been doing 10-20% water changes using these tablets each week and my tank has 50 ppm phosphate and significant algae that I clean each week.
