After an unfortuanate experience with our
DIY CO2 system (drained the entire tank when a air line tube came out) we decided to look into a pressured CO2 system.
We investigated the options here, a cheaper system from Red Sea vs the Dupla and after a couple of quotes we discovered that for a complete CO2 system with ph / co2 controller was going to set us back about $1500 !!
So we checked out systems on eBay. They were cheaper online but still quite pricy. Then we discovered CO2 systems available on ebay.co.uk. Fortunantly I was heading over to Europe in 2 weeks so I pre ordered a complete system from Germany.
- 2 kg CO2 Cylinder
- Propper CO2 tubing
- Magnetic Soleniod
- Glass Reactor/Ceramic Diffuser
- 2 Guage Regulator
- Needle Valve
- One way backflow valve.
all for AU$240 delivered to the UK...
When I got to the UK my cylinder had arrived, a little battered but ok... then I discovered that they had shipped it full. So after emptying 2kg of CO2 into my friends green house, My friend packed it away ready for the trip home to Aust.

The next challenge would be bringing it back. Before we purchased the Cylinder we contacted Qantas and they said it will be fine, provding the cylinder was empty and we could show them the valve was open.
I got to Heathrow early, went to the BA desk, unpacked my cylinder and showed the checkin staff. Luckily I had prior permission, otherwise there was no way I would have managed to get it home. Everything was ok and the cylinder made it back in one peice. On the way home from the air port we poped into our local pet shop and had it filled $19.95 :)

We also picked up a PH/CO2 controller from eBay. It was a simple one that we plug into our Magnetic Solenoid. Works a treat for $110 delivered, not quite the $700 we got quoted in Aust.

Essentially it all connects up something like this...
