Vinegar dozing

[rc1]

Have a 210 gallon with 48 gallon sump. Started dozing vinegar per chart at 50 ml first week and jumped to 100 ml the 2nd week. Have shown no changes what so ever in nitrates. Do I continue 100 ml or go up ?
Glass has developed thin white film today .no algea what so ever in both dt or refugium

Keep going, can take weeks or months to have an effect.
If the chart says go up, then go up.

The white film is likely bacteria growth. You might consider holding at the current daily dose to see what happens to the nitrate level.

What are your NO3 and PO4 levels sitting at currently?
From my experience, (i am still dosing vinegar/vodka mix) it does take a few weeks to really start making changes, but when it did i needed to back off quite a bit as you will bottom out your NO3. I was sitting at 30ppm, once stuff took off it bottomed out. reading constant 0's using salifert kit. I have a 75, with 40 gal sump and was dosing 20-30 ml for about 2-3 weeks, then once it bottomed out, i am just running a maintenance dose of 3ml per day. I feed super heavy and all my coral still looks great, so i know it isn't getting starved. One thing of note, it doesn't use as much PO4 to process that NO3, but it does need some.
