How much do you dose?

[1eyedjyde]

I tried to use randys two part recipe when I started using bulk calcium but I had to dose more than double what I usually had to so I increased the concentration of the calcium to 750g per gallon and the alk is 2 cups of soda ash per gallon as per the brs guide. I now dose 90 mls of cal and alk per day for a 120 gal moderately stocked with special and lps.
