The above statement suggests, a water pump is not needed at all....?

No that wasn't the suggestion at all EG....

It quite clearly said that if you have oxygenation... other than that just by passive water return... the fish will survive a pump failure...

Within a certain time frame anyway... allowing for a pump repair/replacement...

I understand you mentioned if there was aeration but there was no time limit mentioned. Simply I quote, "Oxygenate your tank with an airpump.... and your fish will survive any pump failure.." which makes people think they can have a pump failure and not worry too much because the air pump will keep them alive. Which is not close to true....

No EG.. you're nitpicking... the context was clear... even without a "stipulated" time frame...

Your input on the idea of a timed pump to a siphon activating other siphons within a series of cascading grow beds... would be appreciated...

Nitpicking isn't...

No not "nitpicking" at all John. You stated twice in the same post, fish will survive any pump failure provided the system is aerated,. Considering the flow rate of the water pump is the limiting factor in aerated systems, your statement is completely bogus.

Groan... Paul the scenario was that... with a pump failure... there wouldn't be any flow rate... therefore no aeration... if aeration was soley by passive return of the water...

Yes I didn't stipulate a time frame.. and/or any other caveats... etc etc... blah, blah... that wasn't the point..

This thread is by a new member seeking comment and suggestions for a design for his system...

Contribute in that light please... otherwise start a thread of your own on another subject... or phone me...

all good advice iam confused Rup iv read OBO thread twice trying to work out if its simple enough as i am looking for trouble free cycling if i run stand pipes with overflow and holes for slow feed back to FT would i use a spider and split it to feed 2-3 beds per cycle? this seems the easiest method

OBO doesn't completely drain his IBC growbeds... I'll have to reread his specs...

I'm not convinced that you even need a sequencing solution.. if you utilise the gradient...

Any idea what your fall is??

approx 600mm prob more will laser it the weekend that over 10m if i have to chop ICB to make 300 GB to help drainage np can build frames

lol now you think to tell me how I might contribute after you contribute total rubbish... yeah mate no worries...

Paul... if you haven't anything constructive to add to this members thread... in relation to a possible design... then just quietly bugger off...

Now now, don't make me put my moderator hat on

Ahmen....

I thought it constructive to point out that the water flow rate in an aerated system is one of the primary limiting factors.

A perfectly valid point Paul.. and one you could have made in the context of the thread...

Instead you choose to take something I said in relation to a specific post/context... and to nitpick it, and portray it as something other than what it was... or was intended...

Now enough of highjacking this thread...

Have you any constructive design ideas that you might like to suggest to this member...
