They are both good (sands). This is the pack you prob chucked in the garbage, it's a water purifier like the ones you see on commercials for poorer countries (drinking water). Good call, I wouldn't put that in my tank either, unless I was cycling a tank.![]()
The stuff that's wet in a bag (sand) you don't need to wash for an established tank, the dry you should give a rinse.
Yeah, got those same packets with the flora max substrate I have in my freshwater planted tank
