Has anyone stopped using co2 in their tank?
i have a small 10g that I’ve been using co2 for about a year, somewhere around 25-30ppm.
My plants are nothing exotic; buce, anubias, rotala, some random mosses.
I’ll be in and out this summer, so I decided to shut off my regulator and half my fertilizer amounts. It’s been a week and no influx of algae or other negative effects yet.
I’m thinking I’ll stay co2 free, as none of my plants need it, and my shrimp are probably better off
 
I had a 20 high on the lower level of a stand with simple plants that had co2. At 60 years old getting down to the floor to trim and prune weekly was simply too much of a pain.
i shut off the co2 cold turkey.

The plants transitioned and growth slowed. Still no algae…

It was interesting to see how the plants changed.

Not only does co2 make plants grow faster, but the actual appearance of the plants changes. Leaf size and shape can change, coloration, fleshyness and lushness of the leaves changes I too. A whole host of changes
