Does Sand Blasting Stone come in black or dark gray? I've use number 1 and 3
size sand blasting stones , can get a 50lb bag for like $20. I had good luck with laying a layer of Latrite and capping it with a mix of both sands and grew everything ounce it aged .

A pretty common substrate is the coal slag blasting grit. usually something like 'black diamond', 'black beauty', 'black blast' or whatever. seems to work pretty well if you can find it at a supplier near you.

I don't know the grit sizes off hand, but I'm sure folks will drop in and let you know what works for them.

Where should I look ? What kind of supplier?

 

[Merth]

Tractor supply has it and I think it's a 40-60 grit

Otherwise, Google sandblasting supply and look in your local yellowpages results as well. Make a few calls and I'm sure you can find what you are looking for.

I use Black Beauty blasting grit thanks to recommendations from here. It is primarily black with some green mixed in.

Try also masonry and rock sorts of stores.

Tractor Supply, and 20-40 is the correct grit. Black Diamond is the brand. $7.99 for 50lbs. Lots of folks here use it (myself included).

I have a local store and was looking at there web site, How is there size compared to Eco Compleat ? Does it holds the plants down alright? Do you have a pic of your tank sub.?

I am not familiar with Eco Complete, personally. Maybe someone else could help you there. 20-40 is coarse sand-like. I hope these pix give you an idea.

Nice pic, It is smaller than Eco, I guess I could cap it off with Eco.

You bought this exact stuff and had a pH change? You are the first/only one who has reported this to have happened.

Did you have to rinse this before adding it to the tank?

 

[m00se]

I rinsed it very briefly. That shouldn't make a difference one way or the other though. I could have just dumped it in and let the dust settle. There wasn't that much of it.

How much did you have to use? What size tank? I got a 110g tank 60x18x24

 

[m00se]

I used 100 lbs on a 40b to give approximately 3-4" depth
