I will get some large leafed plants, good idea.
Also, I tried pointing the spraybars up slightly, and then up all the way. The current is way too strong for the betta either way, even with them pointing up straight into the air. And then I'll get water on the light.
What do you suggest I do? Maybe I will try adding another piece onto the spraybar. It came with 2 pieces. One short and another short. I only have one on there now, if I use the other one it will decrease the flow slightly from the one, but still not the overall flow. I'm suprised there's not a way to turn down the flow on the canister. If anyone knows a way please let me know!
Edit: I have added the extension of the spraybar. It helps to reduce the flow. I think once I get enough plants in there the fish will be very happy.
