I am just setting up my first planted tank and bought the Fluval Flora kit. This is what my tank looked like after filling having rinsed the Fluval Stratum!

Three days later it's settled a bit but any disturbance picks up a lot of dust. The filter is also making an awful whirring noise. I'm not off to a great start.
Any tips on whether I should re-rinse the substrate or try a different brand?
