Clear hose lets the light in, hence, algae. Black hose is a better option.

I have clear hose from my pumps, and going from my fludized sand filter
to my UV to my gravel filter, I noticed some algae growing in the hose.
Looks like string algai.

I didn't think it would survive in a 350GPH flow...

Any thoughts on how to clean out? My guess is running a string through
the hose with a brush
