Welcome to the Lab!
After adding several fish, nitrates level raised in our system and maintained at a to high level, between 50 and 100 ppm.
We now have 12 gold fish, between 2 and 3 inches.
In order to solve this issue, we increased the growing surface. We changed the former bio filter (one ft by two feet) for a grow bed more than three times as big. We also added a vertical unit made with the same table.

We planted in the new grow bed different strains of basil, flowers and a cutting of Hand of Buddha.

The nitrates level decreased quickly. This new set up didn’t wait long to proove its efficiency, Henri the Cat thought the new grow bed was a fresh litter and made a nice pee in it.The extra nutrient was absorbed within 5 days.
In order to feed the upper level plants, we installed an ajustable 200 W fluorescent light. At night or when no direct light from the Sun, we lower the hood. When there is direct sun on the plants, we turn it off and raise it with easy-rolls.
Stay tuned …
