How do the living conditions of algae differ in a shallow pond with a sandy bottom and a shallow pond with a muddy bottom?

The water in a reservoir with a sandy bottom is cleaner, not cloudy and there are solid particles to which it is convenient to attach. And in a reservoir with a muddy bottom, illumination is worse due to the smallest silt particles that hang in the water column. Due to the size of the silt – very small particles – it is more difficult to attach to such a bottom, therefore, in such reservoirs, algae are represented mainly by plankton.
