Thats good to know thanks Byron. I was suprised the amount of people who do use the play sand. Must be well worth it tho with it doing such a good job like you say. At a fair chunk less than you pay for other types in fish stores tooSome 8 or 9 years ago I was talked into play sand by members on another forum, and I have never regretted changing over all my tanks. Plants grow very well in sand, it is safe for all fish, it looks natural (play sand does), and it visually creates the suggestion of more space.
