Hey all - Just looking for someone to confirm my math prior to switching two part from Aquavitro (Eight.Four/Calcification) to ESV (B-IONIC Calcium Buffer System).

Neither manufacturer responded to my questions and I am getting discrepancies between reef calculators, so why not ask the community???

Tank is 36g, lets call is 30g for the sake of simplicity and to accommodate for sand and rock. SPS dominant, no sump, lots and lots of stony coral. WC 5g per week with Salinity salt mix.

Alkalinity:
Each 5 mL of eight.four™ added to 80 L (20 US gallons) (standard dose) will raise alkalinity by 0.25meq/L (or 0.7 dKH)

I am currently dosing 9ml of Eight.Four a day to 30g which I calculate to be .84 dKH.
Using the Alk calculator on MarineDepot's web page, if I set dKH to 10 and desired to 10.84 (not my actual desired, just using for easy measurement), I get 11.25 ml or 0.38 fl oz or 2.25 tsp as my new dose, but if I use reef.diystst with the same variables I get 12.1 ml; 0.4 fl oz; 2.4 tsp - confused.

Calcium:
Each 5 mL/70 L (18 US gallons) of Calcification will raise calcium by about 10 mg/L

I am currently dosing 5ml of Calcification a day to 30g which I rounded out to be 5 mg/L or ppm a day (less concerned about being exact with calc as I am with alk).
Using the Calc calculator on MarineDepot, if I set Ca to 400 and desired to 405, I get 9.3 ml; 0.3 fl oz; 1.8 tsp as my new dose, same with the reef.diesyst calculator - not balanced

Questions:
Do these numbers look correct? Any reason why I am not dosing an equal part of each supplement? Do I need to accommodate for the pH buffer in Eight.Four when switching to ESV?

Thank you everyone in advance. Trying my best to switch products with out losing any livestock.
