Tilapia is the most common fish used for aquaponics as well as aquaculture. It grows efficiently and is extremely adaptive to different water conditions, although how big do tilapia get? Furthermore, they have a high survivability rate even in stressful environments. It is a great fish to use for aquaponics, both for beginners and experienced … Read more
Tilapia is a hardy fish that adapts to both freshwater and saltwater environments. According to researchers from the University of California Davis, tilapia has a salt-tolerant gene that makes it immune to salinity stress. Fish are delicate to salinity depending on their internal body chemistry. Salinity can be considered a stressor for most freshwater fish, … Read more
When a fluid passes through a constricted space, it undergoes the Venturi effect. A Venturi water pump utilizes this effect for increased water flow. There are many different engineering applications of this effect, for application in aquaponics we are interested in recirculating and aerating water. Before discussing how to make a Venturi water pump for … Read more
Is the water in your aquaponics system slowly turning basic or getting high pH readings? Some common sources of basicity are the build-up of carbonates (CO32-) from limestone, bicarbonates (HCO3–) from hard tap water, or excess phosphates (PO43-) from over-fertilization. Before you ask how much vinegar you should use to lower the pH of your … Read more
