Airstone and betta
Pretty simple question. I have a betta in a 10 gallon (heavily planted). Everyone is healthy - plants, fish, snails. I don't have a filter and have just been doing weekly water changes. However, I don't like the film on top of the water and I know plants provide O2, but I feel like they're all competing for CO2. So in order to keep up with the gas exchange, I bought a small airstone and popped it in there yesterday, so it's been running for 24 hours or so.
Algae has also become a problem, so I feel a little current will help with this. Here are my issues;
>will the betta hate it? I know they like low/no flow and I don't want him upset.
>will it improve the gas exchange, or just gas-out any CO2?
