The cloudt water is normal! Did some reading about possible causes of cloudy water and turns out it's just normal because of the bacteria I added to the grow stones during setup. The water can be cloudy for up to two weeks until everything gets in balance.
So the pump is working, the fish is swimming and the bacteria is bacteriaing. All is well in the water garden.
So much green today! I'm just blown away by how quickly everything is changing. Aquaponics seems to be vastly outperforming my hydroponics at the same stage. Might be the plants but wow it's growing fast. Will just be a few more days and the whole garden will be in full force.
Exciting times!
