I think I've been dosing vinegar for the better part of three years now, I'd have to look at my log book to be sure and I'm not at home right now.

I got up to a dose of 100 ml/day for a system volume of about 200 gallons. I've struggled to find test kits I trust, so I'm not sure how NO3 and PO4 levels tracked along the way, but I know my hair algae infestation went away a couple of years ago.

Within the last 6 months, I've noticed a problem with pinkish snotty buildup in my sump, and had a problem with the sponge in my Geo media reactor clogging to the point of being unusable.

I've since cut my vinegar dose back to 70 ml/day. The sponges in my filtration don't seem to be clogging as quickly, and the snotty pink goop in my sump has abated somewhat.

I have no idea what caused this clogging problem after a couple of years of dosing. Interestingly enough, about when the clogging problem started I noticed the growth of sponges (purple and white) in the display really took off.
