what i did was jetstream the sand in the bucket and mix it up, make it as murkey as you possibly can, then dump the water out, that way the finer sand that is making the water murkey, will get dumped out but its not like your wasting sand, even though it sounds like that, but you get the idea. thats how i rinsed mine, rinse dump rinse dump etc. and yes your tank will be murkey when you first put the sand in. Its easier however to add the sand then ad the water very gently, and then teh sand doesnt get too stirred up, and not AS cloudy. But then for about a month, everyonce n a while a random bubble will come up out of ur sand. hah cuz it has air pockets.
Anyways i like sand much more than gravel, easier to plant in. Have fun
