End of Discussion on Types of SystemsNext: Nutrient Deficiencies& pH
Nutrient Deficiencies in Aquaponics“Aquaculture effluent typicallysupplies 10 of the 13 requiredplant nutrients in adequateamounts, with only Ca, K and Feneeding supplementation.”(Dr. James Rakocy)

Supplementation (Typical)Note: Keep pH between 6.5 – 7.0when supplementingThese are known to be Fish Safe Iron: Chelated Iron Potassium: Sulfate of Potash Calcium: Calcium Carbonate, Oyster Shells,Crushed Coral, Coral Sand. (pH Buffer)

Water Quality What to Measure:– TAN (Total Ammonia Nitrogen): NH3 & NH4 – Nitrites: NO2- (Toxic)– Nitrates: NO3- (Safe, Plant Food)– pH– kH (Alkalinity, Buffering Capacity)– Dissolved Oxygen (DO)– Temperature
