If you have a favorite bar that you go to you can ask them, they use CO2 for pop and the beer kegs. Maybe they would sell you one and just trade them when you need a refill.

100 watts in a 120 gal? seems to me you need a little more light. Vals can get by on low light but maybe not that low. I have 200 watts over my 75 and and pull at least 6 new plants off of runners a week. If I didn't I wouldn't be able to see any of my other plants.....Do you have CO2 ? big help.
