Nate, what I did was Tee off my return pump back to the fuge area via 3/4 hose where I keep the cheato, the I put an elbow on the end which can be swiveled. Then the flow (from underneath, spins the ball of cheato around).
You may also wish to try a small powerhead, or if your sump is acylic, you can experiment with a redirectional baffle of sorts to direct the flow so as to tumble the cheato.
The easy way is to just manually turn it daily. The stuff you see is actually detritus, which will lead to nitrate issues & maybe the detriment of the algae. I was hoping the addition of pods to my fuge would alleviate this (thinking they would eat the detritus) but I haven't been able to source pods for the experiment.
