In my aquaponics system, I call this 150 gallons water tank as main tank.
This main tank is the heart of the whole system running on the roof...either should we call it sky garden or sky farm is not important but without this tank I will be really busy dealing with challenges...
This tank is
1. Supporting the aqua portion in my aquaponics system;
2. An auto watering system to those plants ie. Grape and passion fruits etc..
3. A place for duckweed growing (in coming weeks)
4. Rain collector
There are two DC water pumps in it, supporting each other and for the future expansion.
