Backyard Aquaponics
A place to discuss aquaponics

Any ideas
Amm/nitrite both 0
Checked with DO meter for the first time as I havent used it before and this system shows 8.4mg/L which is higher than the greenhouse system 7.8
Salinity about 2ppt so off to buy another bag of salt to take it up too 5ish

The one in the pic is now in a 70L bucket with an air stone and 10ppt salt
Salted system to 5ppt
Added another small pump just to pump water from fishtank and splash it back on the surface.
No feed
Now to wait and see

How warm is the water???

Water between about 20 to 29.
The one that had the 10ppt bath is back in the tank and has gone to bottom with the others. They seem to be settling down.
This happened a couple of weekends ago but I put it down to an almighty thunder crack we had just over our backyard. I thought I had been shot it was that loud.
The other thing is both times has happened is just after a large 400L odd topup from the rainwater tanks, so maybe there is something coming off the roof, or in the rainwater tanks that is upsetting them.
Oh yeah, its a newish iron roof
