Vinegar dosing question

[pscheel2]

I have been doing 40 ml of vinegar to my 90 gal and my nitrates have been decreasing. My question is I currently dilute the 40 ml vinegar with RODI and drip it over the course of the day to avoid the ph drop. I have read that vinegar degrades when it is diluted. Would it be ok if I just add the 40 ml straight into the tank? Thanks

I wouldn't do it right away otherwise you may prompt a huge bacterial bloom and wipe out everything.
Start small if you're going to do direct-injections and then build to it.
If you're adding the vinegar to DI water I wouldn't worry about it and continue that method.
In carbon dosing, the slower the better imo.
