Wikipedia is a lot more reliable than other online sources, false information once reported is removed asap, and all information on there is sourced from legitimate websites, usually university websites...swimalong said:The quartz i was recently looking at seemed terrible for aquarium use - lots of little flecks of metallic pieces that easily came off the rocks - reddish, yellow and silver colors through it.
Maybe some variations are better than others, but I would stay away from it. I've heard a good idea is using rock that is absent of any color streaks.
You can't always trust 'wikipedia' either
I think that was a good move... Really the only kind of metal that is safe for aquariums is Iron (rust) that is present on rocks. It is still best you get as much off as possible but what it will do is slowly dissolve, and any dissolved iron will be used by either plants, algae, or be taken out with water changes...swimalong said:True, there is a lot of bad info out there...
Well the quartz i recently looked at seemed kinda harsh, like I said lots of metally shiny flakes coming off it and orange rusty marks, never know it could have been okay but i prefer to stay on the safe side I guess, and I chose another type for my setup.
