Supplemental CO2 for smaller tanks
Hi all. I have a 20H that is low tech today. I'm thinking about adding a CO2 setup. Not going high tech so to speak, just giving a little boost to CO2 levels. I've been adding glut but just don't see the results.
Ideally looking for a system that I can easily conceal (my stand is metal and open underneath). I don't think want to go the DIY route (2 liters + a bubble ladder). Did that years ago and while plants looked good, I don't know that I have the time to mess with keeping the yeast going.
Some of the cartridges out there seem expensive for what they are. Looking for ideas.
