Size and amount of Jeabo Wavemakers?

[cubicalkong]

I have a 150 gallon 6ft. Currently FOWLR Was wondering how much wave Jeabo wave makers I should buy and what size sw-8/sw-15? I mainly want to try and keep crap of the sand and rocks. Placement suggestions are also appreciated

I am a fan of the wifi gyres from them. Scw120 or something like that I would use or the next one up for a 6ft. 2 of them near top, aimed upwards.

Beyond that, I am about to experiment with additional flow due to complicated large aquascape, but from your pic, 2 gyres in their crossflow mode at the "highest" frequency would do great. Mine switch a out every 35 seconds to being on or off, and it keeps the stuff off the sand.
