Today the Aquaponics grade Blue Tilapia were delivered from Lakeway Tilapia and added to the TOL system. The system water tank was 82 degrees and the shipping water bag was about 78 degrees. The system water was pH 7.5 and the shipping bag was pH 7.8. So everything looked good for adding the fingerlings to the system tank. After the Tilapia grow bigger then 15 will be removed and moved to another system.
