Hello Everyone,

I am running into a little problem. I have been adding lemon juice, for pH, and Blood Meal, for Iron, and I have a banana peel for potassium. Recently my ammonia has started to rise, steadily. It was at zero for a few months.

Ammonia: 1.0ppm
Nitrites: 0ppm
Nitrates: 30ppm (probably from blood meal)
pH: ~7.6

In a previous post Hello from Vancouver, British Columbia I have links to pictures of my system.

Keith noted that the lemon juice could be killing the bacteria, what else might cause a systems ammonia to rise. I recently removed my fish tank filter, I assumed that the GB's would have enough bacteria to process the ammonia, but I guess not.

Any ideas? Cheers, Jared
