Backyard Aquaponics
A place to discuss aquaponics

The pea gravel is really previlant through the Perth Hills area, although im not sure of the exact make up it is more iron based as i understand it, Is definitley not Limestone. I have always shyed away from putting to much shell grit or a block of limestone in as a buffer as ive alway been trying to lower the PH.

He lives in Gidge and im in Glen Forrest. so its proabably 15km away...
I will measure the PH soon and then maybe add a little acid, to get it under 8....

I cannot stress enough that you must line the zinc immediately.

There are so many cases of 100% fish deaths due to unlined galvanising.

I decided to remove my fish, put them in a pond i have with Koi, so i can drain my tank and make sure the water is clear of the zinc/galv.
I had a suprise though i had some gold fish and koi in there originally (9 months ago) i thought they had all died as i lost all my original perch. And i hadn't seen any trace of them for at least 6 month.... Anyway they were all in there, they are huge......
But out of my 100 fingerlings i have 20 left, hopefully they will last in the pond.

i was trying to work out why the Ph was high, and i did have some red gum leaves fall in which i did stop but maybe the residual breakdown of the leaves was causing the high PH. I will get the system up with the new water and take some PH measurements. hopefully i will be in the right range this time....

Thanks for everyones input.....

Come on, stop teasing us, where are the pics...

hehe.... i forgot about pics... Ill see what i can do....

yeah pics pics we want pics, especially of your cooling system for keeping trout through summer.

which reminds me, does the coil give off something toxic?
