Live plants improve water quality by absorbing nitrates and providing oxygen. They also reduce stress for your betta by mimicking their natural habitat. Start with hardy species like anubias or java fern.

If you go DIY, keep an eye on the pH swings. Yeast methods can be inconsistent, so test daily until you get a feel for it. A drop checker helps too.

CO2 can be beneficial if you're serious about plant growth. In a 20 gallon, a simple paintball setup or DIY yeast method might be a good start. Just monitor pH and KH to avoid swings.
