Tahiti Moon Sand

That stuff is so fine grained I don't think you can prevent it from gradually sifting down and larger grains becoming exposed.
 
I have it in a 55g and was too lazy to rinse it.I dumped in 3 bags of it and filled up the tank with water.I put in the driftwood and live plants,let it sit for maybe an hour and turned on the filters.I use fertilizer tablets for the plants,and have no problems at all with it.I love it.It looks great,and shows off the fish's colors very well.
 
I had the tahitian moon sand. The water was cloudy for a couple of weeks and then, BAM. Clearness appeared. I recommend it. It's pretty cheap. If your eventually planning to grow plants in it, I would recommend getting Fluorite Sand or something that will eventually benefit you.

Tahitian Moon Sand should be fine. Generally, when vacuuming sand, you will need to lightly go over it, or you can get like a stick and disturbe it a bit while the gravel vac is near the stick.
 
hmmm, I'm not quite sure if you guys understood me so I'll explain things better this time.

I do not want natural plants (they die in the summer, too hot). But I had natural plants before and had some eco complete and some river sand. To not spend so much money in the trade from the 30G tank to the 38G tank I used some eco complete and some river sand and placed the Tahiti Moon Sand on top because I wanted to do an all black tank. Now, I do not want all three to get mixed so I'm not vacumming the substrate, but instead I placed quite a few + than a dozen adult Malaysian Trumpet Snails and probably lots of babies to do the work of moving the substrate for me, but I want to make sure this will be enough to prevent a compacted substrate?
