I'm going to be putting sand in my cory tank,
When I was on groups on Facebook people were saying use kids play sand, it's safe just rinse it out loads
I was wondering if any of you have used play sand, as I don't want to put it in and kill my corys
I'll be doing this when I upgrade there tank which is very soon

Many people use play sand. I preferred construction sand (before I knew about sand blasting sand.) It was a certain type formulated to be for setting driveway pavers. QUIKRETE you can see what I mean by looking it up on the online. Since you aren't in the US you probably don't have this brand.
So another option is pool filter sand.
And another is sand blasting media sand. I have used Garnet sand and it was $18 for 40 or 50 lbs. And Pink purple color. The best thing about using sand blasting sand is that it is really clean. And sorted by grit size.
Here we can get different kinds at farm supply stores, and sand blasting media supply companies, especially if you are in or near a larger city. Otherwise could be kinda expensive through a middleman store.
Here is a Crazy Cory Pic with Garnet sand so you can see the color and size. You can do a search here on AA and you will find my previous threads all about it. "Garnet Sand"
There are many other varieties from the company too. If you aren't up for the pink/purple look there are other gemstone sands and just other brown and black and some whiteish ones as well. You would still need to rinse it but there is almost nothing to rinse. So I would vote for sand blasting sand!
