Ammonia: 3
Nitrite: .75
Nitrate: 80-160
So... ?
Did you dose up to 4ppm last night?
If the pH drop did shock your bacteria, they can take a few days to get back to work, but if you've already gone from 4ppm down to 3...that's a good sign.
I'm surprised your no3 is that high with all the pwc's you've been doing, but that shows there's definitely some conversion going on...also good news
Nothing to do now but sit back and wait. Just test and dose ammo back up when needed.
Hey, at least the pH didn't plummet again, lol.
