Backyard Aquaponics
A place to discuss aquaponics

Just interested to know what people think about this.

We have had a heap of rain lately which has our system at absolutely full water capacity. This in turn is causing our system with its overflow from our large tank to the smaller tank to be going constantly which in turn causes a pump in the smaller tank to pump back into the larger tank.

I have noticed a huge improvement in the trout activity and also plant growth is going off.

So does better oxygenated water cause this or is it just my imagination.

It might be just the fresh water? IMO all AP systems will benefit from periodic partial water changes.
At this time of year (cold water) I don't think oxygen levels would vary much, a DO meter will confirm your thoughts.

Might have to do some tests Embi.....

Can't comment definately on this but I have wondered about the benifit of water flow in FT's for trout also.
I have my pump running continuously 24/7 into 2 GBs above 2FTs and FT1 (the SPtank) flows via SLO into FT2 (the trouttank) and my few trout all sit facing into the in flow current from the SLO. Just as they would in a flowing stream/creek/river I suppose.

Trout love circulating water, if they can swim constantly they will burn more energy, and therefore consume more food, putting on more weight.
