So long story short 3 days ago I tested my water and showed alkalinity was high and showed some aminia. So fast forward to today I changed 35% of the water and my alkalinity drop to 8 something I think but my magnesium drop big time and my phosphate went up very high too. Is this common? I also bought a turbo start 900 to replenish the bacteria I had. But should I now use nopox and start magnesium again and some calcium?
