Salts CaSO4 3.2g, CaCl 2.0g plus a quarter tab campden. Took 1G out and used KRISPY and a 0.9oz dry hop of Herkules.
Based on boiling 8.00 gallonsliters at 1.050 for 30 minutes, this will decrease your wort by 0.50 gallonsliters, bringing your after boil OG to 1.053. You wanted an OG of 1.058. It looks like it will be under.
