Argonite sand will raise your Ph too high for most freshwater fish unless you're keeping african cichlids. I would not use that sand for freshwater. I use play sand from Home Depot. It is inert and won't affect the Ph. It's cheap also...about $5 for a 50 lb bag.

Jeaninel is correct, do not use marine or reef sand in a FW tank. It raises pH, adds minerals (some will) and is counter to good plant growth should you be thinking of plants at some point.

On the cleaning issue, a python will suck up sand so you need to run it slightly above the sand surface when vacuuming the sand substrate. That means you can't get down into the substrate like you can with gravel, so you have to be careful not to allow the sand to compact which it will naturally do if left undisturbed (as will gravel). Compaction causes anaerobic conditions in sand or gravel, but the risk is higher with sand. There are differing opinions on the detrimental effects this can have, but it is a biological and chemical fact that it does occur. Some exists in every aquarium and plant roots make use of it as do anaerobic bacteria, but it can be more prevalent in sand. Keeping the sand thin (in depth) and stirring it can prevent trouble. Peter Hiscock has a good section on all this in his excellent book "An Encyclopedia of Aquarium Plants," and Karen Randall, Rhonda Wilson and many other plant experts have written on this previously in AFI and TFH.

some great information above.....the only thing i would like to add is the importance of rinsing the sand....it's a pain, but well worth it.....also, when doing a weekly water change i use a plastic fork to "comb" the sand with, it releases all the gas pockets that build up Byron was talking about...

When i did my 20L I put the sand in a 5Lb bucket and filled the water 4 inches over the level of the sand and moved in the sand in the bucket, then waited about 5 seconds and dumped the water slowly. Waiting that 5 seconds or so helps to keep all the small particles in suspense while the heavy stuff sinks. I did this baout 20 TIMES!!!! with that single 5 gallon bucket.

Here's an incredibly imformative post done by Tyy on sand subtrates from a few months back....it'll cover everything you want to know!! It's great

so is this sand good

Aqua Chem at Lowe's: 25 lbs. Filter Sand Plus

or
Mosser Lee at Lowe's: Desert Sand Decorative Soil Cover


so anything that says play sand, or pool filter sand is good when i go to my local lowes ( i dont have a home depot around)
I suspect the pool sand (Aqua Chem) may have something chemical in it. The ingredients or info on the back should tell you. But given its claim to do this and that, and the name "Sand PLUS" it sounds like more than just sand and I wouldn't risk it. Pool filter sand can raise pH too, I learned from another forum.

The other, Desert Sand is a soil cover for plants so presumably it is plain sand, but I would want that confirmed before I used it anywhere near my fish. The manufacturer might tell you, but...is that reliable (what do they know or understand about the risks involved for your aquaria)?

If someone else has used these they may have advice.

I agree with the above members, I wouldn't chance it.....just grab a 50lb bag of cheap "play sand", the kind you would use for a sandbox. It's cheap and looks great....like I said before just wash the living hell out of it!!

Yes, play sand all the way. Cheap, inert, looks great, did I say cheap? I use sand in all my tanks now, to me there's no comparison between a nice sand bottom and gravel.

Thanks for the nod Johnny. Maybe that sand post should be stickied...

And remember, RINSE. You will hate it, it will take forever, but done properly you will wind up with a sand bottom that does not make a sand storm in your tank when it's messed with.

I second that...it takes forever and your arm will feel like its going to fall off, but in my 20G I can re-landscape, moves rocks around with no problems at all

No kidding, the rinsing required is excessive. I'm really glad I did my sand substrate over a year ago. Rinsing 100+ pounds of sand required using alot of water. Now that we are on water restriction I would have felt guilty wasting that much water. :-?
