Crushed coral 2mm as a substrate?

[slevesque]

I've been looking around a lot to find a cheap replacement for aragonite sustrate. I looked at home depot and alike for playsand but I only found brown stuff I dont want in my tank. I looked for pulverised limestone with no luck. Industrial quartz is very white and shiny, not sure about that.

Thanks to a connection I have at Hagen, I can have everything they sell for 70% off the retail price (approx). I found this 2mm crushed coral "sand" here
I know people try to avoid the regular 5mm+ crushed coral because it becomes a nutrient trap but the 2mm should be right. what do you think?

It like great sand to me. I would use it.

Great, I know it doesn't have the buffer effect of the aragonite though.

Thanks

Looks great to me! 2mm is a good size. I'd use it as long as it's not a brown sand color.

Eh, the buffer affect of substrate is almost nothing due to the high Ph in our tanks. Don't worry about that. That's what additive's like B-Ionic are for.

Absolutely. I actually bought a couple more 40 lb. bags of Caribsea tonight (seaflor speacial grade), but just because I like the particle size and color of the substrate. It has nothing to do with the buffer affect.

It is for my new 90g
