Can anyone suggest a co2 system?

[squirrelrabbits]

I currently run a hagen system on my 15 gallon (which works fine) but now I need to set up co2 on two 29 gallon tanks and one 55 gallon. I thought I would try DIY on the 29 gallon tanks but for the 55 gallon I was thinking of this:

Is this overkill?

And does anyone have any better suggestions?

Thanks very much.

This is the system I use, of course you don't have to buy it from Ebay, but you can use this as a starter set and can add to the total system as
you go along. I added to this system a solenoid valve and a ph control unit (both JBL) this turns off the CO2 when not needed, and the pH controller can be set to whatever you require.

I hope this is of some help to you.
The conversion from litres to Imp Gallons is 200ltrs=43.9 Gal.
You also get the (Full) CO2 bottle whereas the system you were looking at ment you had to supply your own.
