i need lots of sand. about 200lbs to be exact. anyone have any southdown or know where i can get some?
Isn't that stuff Silica based? I heard that Silica based sands can cause Diatom blooms one after the other.<a href=showthread.php?s=&postid=6882537#post6882537 target=_blank>Originally posted</a> by doodoobrown
i made up my mind to just get the Quickcrete Playsand from home depot. i have been researching and i really dont think it will be that big of a deal. plus its really cheap. im just putting fish in the tank anyway. i will keep everyone posted on how it goes

Well, chemically it is the same as the glass the tank is made out of so maybe the glass is causing the diatom bloom.
