elsaurous Posted November 9, 2012 Report Share Posted November 9, 2012 Just purchased two 3fters I need to fill and was wondering what everyone's take was on gravel/sand from places like landscaping joints and bunnings. Is it safe? Or do I need to be picky? Anywhere else people would recommend for substrate? Link to comment Share on other sites More sharing options...
kasman Posted November 9, 2012 Report Share Posted November 9, 2012 go for your life with either. I have found that landscape yard sand doesnt need as much rinsing if you scoop it from the top as all the silt is washed down being out in the weather. other option is if you want some slightly bigger grained stuff get some pool filter sand.

Betta Posted November 9, 2012 Report Share Posted November 9, 2012 Either is good, if your unsure & want some piece of mind just boil it for a few hours & that should do it Link to comment Share on other sites More sharing options...
