Ph when vodka dosing.

[ocsurferdad]

I have noticed that my ph drops significantly after dosing vodka which tends to make my Nem’s unhappy. I am trying to counterbalance this by dosing soda ash to bring ph back up. Anyone have any advice on calculations for example add 1 Tbsp soda ash for each ml of vodka dosed?

The soda ash dosing is not a good plan. Your alkalinity will go through the roof.

Are you measuring pH, and if so, what changes are you observing?

How much vodka are you dosing to what size tank?

92 gallon plus 10 gallon sump -25% for rock = Treating for 75 gallons. Vodka dosing staged ??0.1ml:25gal = 0.3ml QD for first 3 days then increased dose to 0.3ml:25gal QD for 4 days then raised to 0.5ml:25gal QD for a week.

That small amount of vodka, even fully oxidized won't produce enough CO2 to matter in pH measurement.
