Cheap co2 that works
This is a passive co2 system. You will not see microbubbles of co2 diffusing. The CO2 is dissolved into the water column. If you have a smaller tank (20 gal or less) this is a good system to boost slow growing plants without a large investment.

Got exactly what i ordered
These little tanks last about a 3-4 weeks when used right. there a bit pricey but well worth it to have reliable CO2 and healthy plants

Needs to last longer
Only downfall is that the canisters only last two weeks each

... reservoir once a day one canister will last the better part of a year
If you fill the plastic reservoir once a day one canister will last the better part of a year. Fill it in the morning and then at the end of the day and you're still looking at 5 or 6 months. The plants do really well, the tanks are inexpensive, the whole system is great.

Lasts a few weeks when used properly.
I got this on my 20 gallon and 5 gallon. Both last 3 weeks or more with each cartridge. I fill up the chambers 2-3 times a day. I am not sure how everyone else is using these, but they arent meant for drop check systems, but for passive systems.

Theses last awhile
They last awhile if you stick to using them once a day. Mine lasted me about 2 months with just using it once a day. So definitely worth it. I wouldn't try getting it anywhere else, stick to amazon because it's MUCH cheaper on here, lol. My LFS was selling this for about $25-30.

These CO2 refills are wonderful. My plants are thriving. I can hardly keep up with them. I wanted to see what the difference would be between non-CO2 supported aquarium and one with. This product has allowed me to see the difference. Now I know that I can support my smaller tanks with this product while I look into investing in non-disposable for the larger tanks.
