Yea I was reading about the pollutants on other forums. It seems to be a odd topic because some people like your self say leave it and others say I have this and that and have been fine for years. I think if I rinse the sand in hot tap water it will be fine. I just want the different color and texture and to say this sand if from.... Lol
A co-worker that I got my fish from has a dsb
5-6 inches in his fish only 175 gal
tank, it's been up for 8 years and has sand from all over the world.
The sharks teeth are dull on all corners from erosion on the beach, I'm not concerned with them injuring my fish.
I'll be cautious of what you said and do my best to make smart choices. I don't know what exactly hitch-hikers are so I'll start doing some homework.
