Dosing
The maker doses this by schedule rather than by a fixed potency, so the calculator cannot use it. Follow the directions below.
How it’s used
Plain distilled white vinegar labeled 5% acidity, no additives. Glacial acetic acid can be diluted to 5% but is hazardous.
Cautions
• All carbon-dosing guardrails apply (measurable NO3/PO4, skimmer, O2, ramp, never double doses).
• Dose during daylight when O2 is highest; drip/split to limit pH dips.
• Very high doses can brown corals/anemones; reduce if seen.
• Diluted vinegar is not stable for long; dilute same day.
pH effect: lowers transiently (acid); net alkalinity-neutral once acetate is consumed. Often mixed into kalkwasser to offset kalk's pH rise..
