Help Methods for slowing flow - Oase Filtosmart Thermo 100

[SmartAlec13]

EDIT: Solved. I'll be buying one of the valves JayP links below, from Oase.

My Question: Does anyone know of equipment or methods for slowing flow, specifically for an Oase Filtosmart Thermo 100?

I am setting up a 45U tank for a betta fish, and I know they prefer slower flow. I do not plan on using the outflow spray bar that the filter comes with, instead I'll be using a spin-pipe.

For my Oase Biomaster on my other tank, I am able to reduce the flow by partially unlocking/locking, which closes the openings slightly. But from what I can tell the Filtosmart models don't have this, since they don't have the prefilter that the Biomaster models come with.

I have read online of some people using a ball valve or similar to control the flow. I am hoping some of the bright minds here know a good solution? Thanks!

If the livestock are happy, ie eating and active, and you are not growing BBA on the plants that are directly downstream, those are the main flags

Some plants don't thrive if they're being battered about but you should be able to tell by watching them grow

Ah S**t so that is why I still have BBA in a few spots.

Glad my double taps arrived this week then, so I can actually limit the flow more properly.
