Backyard Aquaponics
A place to discuss aquaponics

good points... perhaps if I install one more irrigation 'arm' than one usually would it would help spread the water better...?

Yes - would be worth putting in more grid I reckon AM.

*sigh*
up goes the cost, but I will have the power when I get my pump from Murray to run more grid than normal....

Don't just take my word for it AM - see what others think. Is just my personal experience and is on a very small scale.

After hearing what a number of people have said on here i would agree with you VB... I guess anothe 2m of PVC wont brak the bank, just being dramatic

dump your bag of clay balls into a rubbish bin and fill with water and leave for a few days.

Remove the floaters and use the sinkers

replace the floaters back into the bin and fill again. check in a week, you will have more sinkers.

EB, in reading your book I've had a closer look at your pea gravel. Is it bauxite? The colour looks right.

If it is, it should be available to AM in Cairns fairly easily. When I was at school in Cairns the council used to use it for landscaping purposes.

why does bauxite sound so farmilliar? Is it used in making metal or something? i remember talking to someone about bauxite ages ago....or it was a dream...

If memory serves me correctly it is the aluminium ore ?

yeah that sits right with my memory.....and i remember what it was from, a stock/ore/mining game

(i should probably try not to go so far off topic)

yup, that's it. heaps of it in FNQ

but did we not decide that aluminium was not that good for aqua... or is the peanut gallery still out on that one?

but to get back to my question... is the media that EB is using, the pea gravel, bauxite?

Think he uses pea gravel and that Hydrotron. Whats Bauxite?

sorry, had to giggle for the circular discussion...

bauxite is the ore that aluminium is extracted from, also a clay called kaolin.

it is a fairly common ore in Far North Queensland and parts of Western Australia (among others)
