I check for Ammonia, Nitrite, Nitrate and PH.  Once you system settles down after a few months, you'll hardly need to check at all.

Hi Andrew, belated thanks to the reply. We've had a few weekends away, but now getting down to it. Dave has the bell syphoning going great guns ( after a bit of tweeking) & I've planted out the bed. I've introduced some gudgeons just to have something in the tank. I used water from my turtle tank as well as tap water. Now doing pH testing... Any tips on water testing? Is the GH & KH test kit necessary? We'd love to have a look at your system one weekend. Thanks for the offer!

Yes Angela, Jade Perch are great fish to raise and have a lovely taste and delicate texture.

Comment by Andrew Cumberland on April 15, 2016 at 20:31

Angela - I would go with Jade Perch not Silver Perch.  The silvers are a lot less stable in terms of food and general temperament.  I'd be happy to show you my set up at McDowall if you want to see it.

Hi, we've just cut our tank down & bought our rocks(?) watched a few inspiring things on the internet. Ready to go.... Any tips? I've been researching fish. Any suggestions for Brisbane? I'm thinking silver perch. Can't wait... I love the whole system. I'd be happy to chat with peoe who have them running.
Cheers, Angela

I agree with your son Andy.

Comment by Andrew Cumberland on April 3, 2015 at 23:23

Now, I'm not having a go here Elaine, but you know - my (then) teenage son said to me, "Dad, if you can't kill it yourself to eat, why would let someone else do it for you and pretend it's okay?"  He became a vegetarian (and still is in his mid-20s). 

It was one of those "out of the mouth of babes" comments.  I'm happy with the "humanity" of how I can kill fish.  I reckon I could do a chicken humanely as well, but My Rozzie would kill me (in the most inhumane way!) if I did one of ours.  However, I doubt if I could kill a cow, pig or sheep.  I'm actually starting to wonder about what that is telling me.  

But no, I am NOT concerned my greens and veg suffer!  LOL. 

Comment by Elaine de Saxe on April 3, 2015 at 23:03

Killing is gruesome however humane. The connection between what you did and the Japs and the Dolphins was just too much. Couldn't watch rest of film. Now I know I would never have aquaponics with a view to eating the fish.

Regret to admit I'm an 'outta sight, outta mind' kinda person.

Comment by Andrew Cumberland on April 3, 2015 at 22:21

I just use it as a "back-up" to the ice, Elaine.  

I can tell you for sure that lowering the body temperature of a fish like that will kill it.  They just go to sleep as their organs shut down.  However, I never want to risk a fish waking up mid-clean, hence I add the Iki-jimi.  

How can I be so sure?  Google research?  Nope, I've raised and bred tropical fish for more than 20 years.  Trust me, I know my fish.  

What we did might look bad but it is far more humane than how they kill your shop bought beef and chickens. 

Comment by Elaine de Saxe on April 3, 2015 at 22:06

That Japanese method of spiking through the brain really looks horrid. Reminds me of the awful people who herd the Dolphins into Taiji and do that to kill them. The lucky ones get killed the unlucky ones get sold into slavery at 'marine parks'.
