SeachemFlourite Sand, 15.4 lb

The substrate is good, but it was advertised as black sand, it is actually red. Looks like ground up lava rock.

I had a bad experience with this. I ended up washing this over and over like people online said to do but this specific version of fluorite no matter what for me always gets dusty. I had this originally in a 15 gallon tank but removed it for being to mucky as it was covering up all my plants and drift wood with red dust it looked bad. I contemplated of throwing it away then I just ended up putting it on a 10 gallon spare tank with just dragon stone ( it does look nice once it settle down and isn't blowing all around). But before I did that I did another really good wash. This is the only Flourite Sand I had issues with and I believe its the size of the clay that just makes it prone to become a dust storm compare to normal Flourite Sand. So just be careful if anyone is going to buy this maybe you will have better luck or maybe I didn't wash this enough I don't know.

Flourite sand is great if you cap it with a regular aquarium sand. In rhetanks I have done this with, my root plants do much better in. Just top it with some regular sand of your choice and you won't have to worry about rinsing it at all...unless you fill your tank up like a maniac anyways. Half and half ratio really well. This is beneficial if you are using root tabs of some sort....Great for crypts and swords that really benefit from a deeper sand bed. 1 inch flourite sand...2 inches regular sand...half and half ...or whatever you like really. Just make sure there's an inch cap of some other regular aquarium sand at least, and you won't have to worry about dust at all...especially if you choose a finer sand.Hope this helps people.. Just gotta problem solve a little bit. Plus .it's cheaper this way...unless you are dealing with a really small aquarium.
