Backyard Aquaponics

So the Calcium is just in the normal tap water???
And yes we did fill the tanks to much in the beginning when we tried to figure out how big to open the taps between the 3 growbeds. So that explains that. At the moment things are really looking good.
Another water test: PH-7.6 (that seems to stay the same)
Ammo-0
Nitrite-0
Nitrate-20
The fish seems happy and they are eating, still a bit scared of me

Perch always will be.

Wether its calcium or salts, it does not hurt anything. The rain usually removes it.

I had problems with iron deficiency, I got some spray which I used twice, I added a seaweed extract and put some rusty nails in the drain. After a few days, things are looking much greener, now I'm just trying to figure out what worked.
