Backyard Aquaponics
A place to discuss aquaponics

Think there are 10 in this tank but more in the pool.

Had a interesting thing happen today. The pump failed so no water was moving through the fingerlying tank. The shaft was in 2 bits when I took the pump apart. Not sure how many hrs the water was off for but the gb was empty and the water level was below the overflow in the tanks so it could have been since yesterday.

Stainless shaft?

Plastic %#&@. Was only a 1000lpr pump.

Hmm, never had a plastic one...I have had stainless shafts fail, best so far have been ceramic, they just last and last.

Moved all the fingerlings today. Water was getting cold and some of the little silvers where karking it. Moving them into the pool was easy, just remove the standpipe and guard and let them go down the 40mm PVC into the pool. Water is all the same and they like the larger area. So 80+ days with up to 400ish fingerlings in 380ltrs of water. I was going to leave the catfish and goldies but its too hard to pick out the silvers among the other fish. When the tank was empty you could see how thick the biofilm was around the walls and bottom. It was interesting to see how fast the bacteria grows with high o2 and a constant food source.
