Hello,
Troughout my lfs around, I'm not able to find the substrates you use like onyx, eco-complete, laterit, vs... What I can find are regular sand, different sized and colored gravels. Unfortunately lfs around here are not very much into this kind of varieties. So why I'm sending this post; as I can not find material for substrat I would like to use anything (sand, gravel or mix) that will suit my viewing pleasure. But I would like to know how I can be sure that the material I will use will not release anything to water column ar be harmful at any aspects. Is there any method for testing the material before use? etc...
Thanks to all,
