Does all pool filter sand have silica in it. I am changing my substrate today. And I dont want to put the wrong thing in it. I have heard mixed reviews on sand with silica in it. Any help is appreciated.
 
It should be labled on the bag. If it is silica, just use common sense. :D When I use it I wear a paper dust mask and safety glasses (goggle type), and gloves. :D
 
Just make sure and stir it up 1 or 2 times a week or you will get anaerobic spots. I had it for a while but now prefer a darker substrate
