Looks good, but 2 questions....

The rubbish bin sump really needs to be lined - the galvanising will leach into the system - a few fish kills have been attributed to this.

Why run the plumbing up so high? Would it be wasteful on power / harder on the pump? Handy for climbing things up though I suppose.

Hi Bret,
So far so good. One expensive set up you have there. How many fish do you intend to grow? Why the choice of 40mm PVC a bit over kill is it?

G'DAY Outbackozzie,thanks for the compliment,to answer your queery on the Gal bin, a plumber told me it would be no worries,i guess i worked off the fact that i have been drinking water out of Gal tanks for years and havent gone belly up yet,so hopefully the fish wont,I have seen some grow beds made out of Galvanised tanks and thought fair enough.the height of my plumbing is due to the fact that I am over 6 foot tall and it affords me the luxury of walking freely underneath it all without having to do the limbo.the pump more than handles the head,the excess water is pumped straight back to the fish tank to help with airation,I'm happy,and hopefully the fish will be too,I didnt really factor the cost of electricity into my system as unfortunately it is a neccesity,like putting petrol in our cars to make them go.
regards Brett

Nearly all Gal tanks used in AP are Aqualined, AP water tends to be more acidifying than normal tank water.

40mm is the standard size for big setups. Especially for flows over 4000lph.

Hi jonathon,so far so good,yep getting close to 7 grand,not much to spend your money on in emerald .I'm looking at it as a hobby and therefore hopefully money well spent.The 40 mm pressure pipe probably is a bit of overkill,I think it's just my nature, if i'm going to do something i usually do it pretty big,it wont break in a hurry anyway.I will probably grow some jade perch first up not sure about how many though just yet, i'd probably rather kill 150 than 300 at my first go, wait and see.

Ta for pointing that out outback,could i just use a heavy plastic bag of some sort in the bin.

[Outbackozzie]

Best thing would be some potable paint on liner. Rubbish bags would do it as well, but are they any safer? - its up to you how far to go.

Its just that people with unlined gal tanks seem to have fish kills, until the tanks are removed, usually happens around the 6 month mark....and they rust relatively quickly in AP.

Hi Brett,

One thing I would be a little concerned about is the size of the return pipe from the beds to the sump. I have a similar setup and if more than one bed flushes the autosiphon at the same time the water can back up and leak. If at all possible can you run the large pipe all the way to the sump?
