Well after 24 hours of CO2 from a bottle of yeast ph has dropped to a more
reasonable 6.8 just before the lights went on for for the day. However my
yellow and brown spots are still growing bigger.
Should I increase the hardness to say 80 or 100 ppm? Note 55 ppm relates
to about 3.3 grams per gallon or a bit less. And if so how much baking
soda should I use for this?
