Hi I have a Jewel Rio 240 which has a Bioflow M 600 l/h. Would you recommend a wave maker as well or would this be too much flow? If so which size would you recommend?

Rule of thumb is you want around 30 times the volume for flow. So 240L x 30 = 7200Lph. Jecod is good for value. They're not the best out there, but provide a lot of flow for their size, and they're way cheaper than the top brands.

Maybe one of these:

As above, you want more flow. In my old rio 240 i had the 1000lph pump, 2x 2700lph wave makers and a RW-8.

Thanks guys, since I’ve installed the wave maker detritus build up  has massively decreased as it’s getting lifted up into the filter. In your opinion is there an optimum positioning?

Good question I keep moving the direction as I'm not sure!

Fluid dynamics are insanely complicated even for something as uniform as a pipe. Working out where the flow goes is better done by trial and error. I've been following the theory of creating a gyre in the tank for a long time now, and seems fine to me.
