Backyard Aquaponics Update

Almost a year plus in my forays into Aquaponics. The only regret is I couldn't spend much time tendering to the setup due to my outstation work commitment.

Safe to say my current system setup is working just fine.
IBC fish tank is full of 50+ tilapias of various sizes from 1 inch to 10 inch.
The main growbed producing an endless supply of kangkung, chilis, various herbs (mint, basil, chives and pegaga) 3 pods of cabbage are sprouting.
20 gallon barrel is used as water storage and fingerlings
Recently added 15 gallon sump tank for the pump
