Another question, how much inflow into the fish tank can the standpipe handle before it gets too much for a gravity flow out, esp once the outflow into the growbeds is restricted with irigation grid etc

Would take heaps the way I have set it up because the height of the pipe going into the bed is about 30-40cm lower than the top of the standpipe. Of couse the level that the standpipe is full at is equivalent to the highest level that I have my piping going to the grow-bed. The way I have it - this is equivalent to the height where the water goes into the bed.

Stu - here are some pictures which make the levels clearer. If the amount of water supplied was a bit high for the outlet pipe to handle - the level in the fish tank standpipe would rise to a level higher than the outpipe which would result in a higher pressure and more outflow.

You will see that at the moment the water is going into the standpipe through some holes close to the top instead of over the top of the pipe. I have done this as a temporary thing (until I put the outer pipe on) cause it helped clear up some of the solids floating around in the tank initialy.

I like it VB, looks great.

I love your new system VB, nice, clean, and neat! It will serve you well for sure!

Hi VB nice looking system on the fish tank are you going to have a nother pipe over the drain [acqualture style] to remove the solids also an overall picture would be good

Thanks for the positive comments guys.



Look back to page 23 F&F - plenty of pics there. Yes I will have a 100mm pipe over the 80mm (alla aquaculture). I just have to buy a length this week and install it. I have a full description on page 23 also.

How the hell did i miss those 2 pages

Nice system VB... I like it. Wish I could get those tanks here.

Lookin good VB.

Have you pee'd in it yet

Don't need to mate - have heaps of nutes without that. Need to spend some time on grow-beds now :-)

It's actually good to see your system happening for you
and it also serves as a reminder to get off my a@#e and get MKII underway here

P.S. GO ON, PEE IN IT

Was very tempted on the weekend - spend hours on the Saturday trying to get the siphon to work properly (break by itself). Running water all the time. Had to kept going off to pee.

I second that... but no pics of that please

BTW, nice looking setup!

For some reason I was just thinking about this question raised by Stu



and my response



Just wanted to clarify that regulating the water going to each bed is aonly really necessary to the extent of keeping the flow within the parameters taht your autosiphon will work. One of the beauties of using and autosiphon is that the bed will drain once it fills - doesn't matter if you have beds filling and draining at different speeds. This is not the case is sytems where you rely on a timer - as the beds will all drain at the same time - regardless of whether they have filled properly.
