Black sand
what types of black sand is out there for freshwater tropical tanks? I've heard tahitian moon sand and blasting sand talked about - any others? What are the ups and downs?

..anybody? Someone has to have or know something about black sand.

I do know the company Sea-Chem makes a black sand that i have used in 2 of my tanks but i cant remember the correct name of it.............its not really a sand, but more like a very finely crushed stone.........I dont know how cories would be with it, it might be a little too sharp for their barbs..........I am currently using it in a 37 gallon hexagon tank with rasboras and danios and a 10 gallon shrimp colony tank with no problems.............The blue pearl shrimp contrasting against the black substrate makes their colors more pronounced...........

I've got Black Tahitian Moon Sand in 2 of my 3 tanks and I love it. No down side to it that I've experienced. I also added an additional layer of Seachem Black Flourite in the very back of my larger display tank to assist in plant growth. I believe this is the product Fishin Pole is referring to. Flourite is a fracted, stable porous clay gravel. The Flourite does have some sharp edges to it so it's not something I'd use for the entire tank as far as substrate since I keep alot of bottom dwellers in this tank. Eco-Complete comes in a darker version which is something I may try in a smaller tank once I get around to setting it up.

Are you going with a planted tank? Keeping any cories or any other "sensitive to substrate" fish?

AK, you are correct with the black substrate i am using.....Just couldnt remember the correct name

Thanks guys. I had briefly looked into the fluorite but quickly came to the same conclusion we have here - it is not for sensitive bottom dwellers.

Sorry, i meant to put this in my first post - but yes, i will have 6 albino cories, blind cave tetras (which to my knowledge will surf the substrate for food as well), and maybe a few khuli loaches. I haven't decided what tank the loaches are going in, but i will definitely have cories.

Sounds like we all agree fluorite is not the best for cories so i would prefer going with something else. From what i remember Tahitian moon sand is all inert right? If there are benefits to it i will go that route. If i can confirm that blasting sand is 100% safe and find out the TMS doesn't have any beneficial additives i will probably go with it since they are more or less the same thing.

Thanks both for the input, it is greatly appreciated.

Here makes the tahitian, which has a good list of acceptable fish to that exact substrate.

becareful though, alot of black sand is derived from iron which will mess with the water chemistry

Caribsea says TMS is not soft belly safe. Anyone have info experience either way?

Guess we still have nobody with experience on blasting sand?

whitedevil 05-13-2009 04:53 AM

I got the marine sand over the TMS because of the fish I keep, catfish barbells wont last, neither will soft bellies, the black is sharper sand then Marine sand is but now you can go to that first site and see about their black sand. I dont think thats TMS.
