I recently changed one of my tanks from the black tahitian moon sand to play sand because I wanted a lighter color (but not pure white.)
I've noticed that there is sand in the filters now when I clean them and the plants will often have very fine sand on the leaves. The filter intakes are about 5-6 inches from the sand so it's not sucking it off the bottom. I think it's from the cories stirring up the sand when they feed.
The play sand is much, much finer than the black moon sand. It's not harmful (to the fish) to have the fine particles of sand moving about in the water, right? The conversion was about a month ago and the water still has a slight haze. I'm thinking the haze may just be fine particles of sand suspended in water. Does this ever clear? Anyone else have these issues with playsand?
