problem maintaining proper parameters

[Beverly]

I would break it down into thirds, which would be 30 teaspoons, mix it with RO and add one third each day. I edited my earlier post, so you may get an idea of how much to add at a time. I did not dump the 20 mls in all at once. I used a 10 ml large syringe and added it in dribbles where the water movement was highest and second highest.
