Thank you! I actually have pictures, but you can't see the rocks/sizes very well. None of them were rounded, though. I think I'll get 1kg of basalt for my echies, and another random bag for "experiments".

I don't know how is the chicken grit sized where you live, but size #5 would be huge. Growers size, or size #2 is what is recommended. Find out the size before purchasing.

On the bags, I see something mentioning 1 - 5 cm. Is that size of rocks? - if so, that would be way too big. Or is it referring to the thickness of the layer for the tank?

Edit: False alarm! Just found out that camada = layer, so that is not size of particulates...:) but thickness of the layer for the bottom of aquarium tank...

rina - well, I wouldn't either - no chicken grit around here ^^ and the thread I quoted is really, really old, so maybe it's misspelled or outdated?

I found an old picture with the rocks I use currently, and the size is pretty much similar, one of the "stream bed" quartz rocks were just slightly larger.

That looks just a bit large but hard to judge the size. Here is what I use in the mix (size #2 as I said in previous post):

I was reading about laterite, either soil or rock. Seems to me that the laterite rock is in the mix. Supposedly rich in iron and aluminium...

Rina,

I grew up in Rio; am native speaker of Portuguese - 1 - 5 cm is referring to the thickness of LAYER recommended being placed at bottom of aquarium (not their size).

de Nada (means you're welcome ;>)

Thanks, I google-translated few words and realized that's what they mean :) Should have done it before posting, right?
