Backyard Aquaponics
A place to discuss aquaponics

I have 300 metres of 19mm poly and about midday run the pump for 6 1/2 minutes which produces temps of 40 - 45 deg and just over 100 litres of hot water which will raise my water temp from about 23 deg to 24 deg. I do this again about 2.30 for another 100 litres.

So I think their 80 metres is not going to account for much, more like the couple of 5000W heaters they have running, and dont have to justify the elect bill.

So it basically comes down to 10000L supporting 1600 lettuces. Any idea how many barras in the two 5000L?

Watch out in summer you`ll need to cover up that poly, I wish I had taken pics of mine that i had on top of my pergola, the left over water in the pipe must have boiled... It literaly blew holes out and then colapsed (flatened out). It was in direct sunlight like yours chainsaw, I`d hate to see all that pipe go to waste
