Algae is the most probable culprit. It could also just be settled particulates. Either way a good shock treatment followed by vacuuming should get rid of it.

These types of pools usually do not have any chemicals in it like clorine so the plain water if it is just sitting there for a while develops an algae which becomes slimy since the watre is not treated and will only get worse until the water turns green and slimy.

this can be caused by two thing's in your pool alot of chlorine or algae. some time's people paint plaster pool's and use basic pool paint and sealer without slip gaurd or other chemical's added to resist slipping or the slimy fealing. some times it can also be a pump not filtering proper leaving small particles to settle.
