I've got some questions and would appreciate whatever comments.
my nitrates were off the charts 2 mos ago, so I emulated Randys carbon dosing.
Now, after 2 mos nitrates are down to 20. Twice I tried to include vinegar in the regimen and both times had to stop because even small additions of 1ml per 50 gal per week caused a bloom of (bacteria?) white slime.
I also dose trace ammounts of Kalkwasser. Even with massive waterchanges my dKh is now at 14.
So what do you guys think? Dose vinegar anyway? Increase?
