Ratz Calcium Reactor

[macpegg]

Just purchased this fine piece of equipment. And now need CO2, i do not fancy paying £150 for a CO2 kit. Has anyone set up a make shift co2 reactor for a marine setup? I will prob have to buy the real thing, especially for measuring the co2 levels for PH. But i thought i'd ask 1st incase sum1 has successfully attempted this and made it work..

thanx

if you have a friend who works in a pub could get him/her to half inch a bottle, regulater and valve for you?
