I agree with Murray that some sort of deeper plastic container over the fish tank would be the go for your test system. I did something similar over mine, filling it with hydroton (expanded clay balls) which are available at hyroponic stores ($35 for 50 litres is a good price - though sometimes you can be charged up to $50).

As you are probably aware the grow bed medium will also house the bacteria that convert ammonia to nitrite and nitrite to nitrate. The job of the plants is then to remove the nitrate. No more water changes once it is all working :-).

Unless you already have a biological filter running in your tank, then the grow-bed medium is a very important element. When I had a temporary grow-bed on top of my fish tank while getting 20 perch fingerlings ready to go in the pond, I just ran the grow-bed by having the water go to the bed after leaving the canister filter and then returning to the tank directly through a drain in the grow-bed. I ran it continuous flow.

Anyway - good luck. I predict it will not be long before you go bigger.

been reading the book ... between Christmas prep and 8yo birthday party prep ...

So, a deeper container above the tank. Would 20 cm do?
And, I've had vermiculite in the shallower bed. It's begun to clog some of the holes. Is there something else that's light that I can use? I kinda get nervous about a lot of weight sitting on the top of the tank.
OR, is it time to do some pipe attaching ... Having minimal time, poking holes int eh bottom seemed the easiest thing to do. Does it just not work? :(

l3nny, sounds like you have a growbed above an aquarium setup Sorry if you've already posted a description elsewhere.

If you've got a small setup running cont. flow then hydroton expanded clay balls are light and work well for a small setup.

Lenny I am also a Qld homeschooling Mum.

I heard about Aquaponics through the Permaculture and ALS forums.

I'm Bel and I live on the Atherton Tablelands. We're currently looking for a property to buy and gardening the old fashioned way. ;)

Hubby is keen to learn more about aquaponics so I think I'm going to buy *the book*

Welcome Bella.

Couldn't home schooling and aquaponics work wonderful together!!! Mine are a little young to get really into it yet - 8,6,2,5mths. But the dream lives strong, even if only currently as a growbed above a tropical fish tank by an eastern window. Ah, but who knows what Christmas may bring?! I'm due for a treat or three!

Unfortunately the baby / 2yo combination is making it hard for us to fulfil our legal requirements of work completion and so the homeschooling looks like it's going to have to lay to rest for a year, or semester. It's heart breaking, but hey, I can try to soothe the pain etc by thinking of the setup I'll have by the following year when they're back at home to really enjoy it?

I guess we'll survive. Or not. :roll:

Lenny
