Aquaponics

Good fish suitable for aquaponics

Below are the list of fish suitable for aquaponics

1. Koi - can feed them almost anything
2. Cat fish - can feed them anything (prefer low protein food) but make sure that you turn off lights in the night. They are active in the night.
3. Goldfish - can feed anything. Have been domesticated for a long peridos of time. Also, this fish can share the tank along side Apple Snail.
4. Carp - More like Koi. Koi is a inbred carp.
5. Tilapia - Make sure that a few generations of Tilapia fish are not used for eating/sale as they may have parasites due to the bad fish feed being fed to these fish in commercial tilapia grow centers.

   Compost tea with aquaponics

Though ocompost tea does not help in iron deficiency in the first few days, it will help in a aged system with lower PH. The video does not show how this compost tea is applied. One method to apply the compost tea is by spraying the compost tea on the plants of a aquaponics system. Also, using compost tea from a worm based compost is far better than the normal composting procedure as the risk.
