Fluval Spec III help?

Hi, I am very new to this website. Well, not new, I always look here for info, but I just made an account.

Anyways, I have a Fluval Spec III with 3 Emerald Eye Rasboras from my 10 gallon semi-planted aquarium. That one is all good and cycled and has been for a year. I also added plenty of filter media to the Spec to jump start the cycle. The Spec is nice and all, and has a high flow rate even on it's lowest setting. The rasboras love it. However, I was maybe thinking of putting a Betta in there. I learned a trick from a guy on here that put a Fluval Edge Prefilter Sponge on the spout. I tried it and it slowed the flow so much that the water was somewhat stagnate even with the flow rate at its highest setting. I was wanting to put a Betta in there since the flow is extremely low and they are somewhat used to semi-stagnate water.

What are your opinions on this? Should I put the rasboras back in the 10 gallon and put a Betta in the Spec and add a sponge to the outflow? Or should I keep the rasboras in the Spec?

I would say move the Emerald Eye Rasboras to the 10 so they can have the big space and put in a betta with sponge in the Fluval.

Just my thoughts.

^^ Agreed. Bettas do NOT like a high flow rate. Most betta owners with Spec tanks put the flow rate on the lowest setting AND further restrict the outflow a bit to slow it down. As long as you can feel water moving out of the outflow, there will be enough water movement to filter the tank. May not be as much as your other fish like, but your betta will be happy.
