I just bought pool filter sand for my tank and found out that it is silica sand. I think I read that silica sand was too fine for planting. Is there some other choice? I also am looking for something darker to blend with this does anyone have some suggestions?
Your site has been a big help to me so far.
My PFS is light tan in color, just like everyone else's that I have seen. Grain size is much larger than other sands I have looked at. And to calm your nerves a bit, my plants seem to be doing just fine in it. Lots of folks use it in planted tanks.
Below is an image of what my PFS looks like, just for comparison. This was shortly after the switch, so it's still nice and clean. The sand has turned a darker color since then (almost 4 months since).
The amount of light will also have an impact on the color of the sand. I use PFS in my tank and the stuff works great. I have plants and they seem to be doing just fine. The sand is great because most of it won't get sucked up when siphoning and the stuff that does is really fine and would cloud the water anyway if the sand was disturbed.
