A great alternative to a full blown CO2 system
I use these on 5 small 5 gallon planted tanks, 1x10 gallon, 1x20 gallon and 1x38 gallon tanks. Once you get the hang of adjusting the bubble counter to 1 bubble every 2 seconds they REALLY work! Even with LED lighting, ALL my plants have taken off in terms of growth and I even furnished 3 of my 5 gallon Betta tanks with cuttings from the other tanks! They are a little bit on the pricey side, and yes, a DIY, or paintball or even a full CO2 system with all the gadgetry would perhaps be cheaper in the long run on the 2 larger tanks, but on the small tanks; can't be beat. You CAN get the smaller 45g cartridges and adapter, but if you do the math, the 95g are more cost effective; the 45g cartridges WON'T fit in the 95g CO2 release unit; different thread.
