Substrate ?

I'm new to the hobby and I'm going to set up a 40gb with co2. I'm looking towards sand type substrates in order for my Cory's to poke around in. How is the fluorite black sand? I'm thinking of blasting sand or 3m color quarts also. Any information or experiences will be appreciated. Thanks

I liked fluorite black, it's pretty abrasive tho, can scratch glass and for sure plexi or acrylic.
Plant roots love it, and it's heavy to it holds them down nicely. The color is not very even but that loos a but more natural than other uniform black sands.

Flourite black sand is VERY dirty and will cloud your water like nobody's business. You might be able to get around this by rinsing the sand first, but I have only used 1 bag of it and I did not.

It clouds the water in the beginning if you disturbe it a lot, I would just be very careful when filling up. I had a nice canister so I guess that helped.

I thought it wasn't available anymore? Anyhow I used to use 3M Colorquartz with dwarf loaches. I don't know if they dig as much as cories but their barbels always looked good. You will need to rinse it but it's not too bad.

3M Colorquartz is a very dense material, and very clean. It is my understanding it is off the market or perhaps being sold under a new name. There are similar products that are available. Look for the Pebbletech product line.

If you have access to 3M Colorquartz or equal, it is a nice material. I sure do not think it has any cationic exchange capacity, though. It is easiest to describe it as a very uniform sand or very fine gravel. It was available in many colors. I have one tank with the black Colorquartz. Really sharp looking.

My mistake it's not the 3m brand. Thanks for the info. On another note would you have to use root tabs on substrates that have a high cec like Eco complete or something along that line?

I wouldnt recommend anything with abrasive edges if you want cories to poke around in it. I would be afraid it would hurt the barbuels or whatever their called. I know pfs has rounder edges, not sure about blasting sand.
