An update to my AP system: it's been almost 6 months since I established my system, I see alot of improvements in plant growth as well as the fish. So far I was successful in growing lettuce, pepper cress, green beans and tomatoes. I am experimenting now on growing cucumbers. My AP system is still used for experimental purposes, it is located oudoors on my south East balcony in Santa Barbara area, Southern California, unfortunately it is illegal to grow tilapia here, so I am growing goldfish…

Learned today that the way to control ammonia levels is to stop feeding the fish.  We were overfeeding and that drove ammonia levels really high in the 8+ ppm range (tubes on the left of photo). Taking what I learned in Knoxville, I stopped feeding the fish for two days and the tubes to the right illustrate how depriving the fish for two days dropped…

Can't seem to get anything accomplished this week due to all of the rain. Bought 10 bags of Stalite on Saturday and have not been able to rinse them and add them to my grow bed. Maybe later today, since they are forecasting for the rains to subside.

Anxious to get my plants going and finish cycling up my system.
