Well, I finally rushed out to buy potassium nitrate. I added one teaspoon to my 75 gallons which had shown zero nitrates. An hour later: zero nitrates.
Hmmm. Add another teaspoon. Got lots of plants (some turning brown due to lack of nitrate I figure), so overdosing not likely. Besides a water change can fix an OD. Later: still no noticible amount of nitrate. Zero. Absolutely clear when it should be pink. It's a new Hagen test kit that has done well on other tests so far. Before I add more stump remover, I thought I'd let the collective wisdom of this board weigh in. I gotta go get some enema stuff. Do I just ask for the rectal aisle?
