I've never used playsand myself, but I've heard it's not the best sand to use because it tends to compact over time. Pool filter sand is said to work well. It has no nutrients, so you would need to dose the water column and perhaps use root tabs for those plants that are heavy root feeders.
contains silicates which causes brown diatoms/algae, atleast this is what i experienced. Plants will grow in the stuff but over time i experienced algae on the surface of the sand and on the glass where the sand sits. but none on my flourite black gravel (both were used in the same tank)
