    it is aquarium safe, its usually sold as filter material..

    it doesnt look very natural, but if you dont mind that or can fix that up some how, then i dont see why you cant use it..

    Cool thanks WBS I changed the substrate in my tiger barbs tank to playsand and added white river stones also. So it is very light. Where after I noticed that they not very happy at all. As soonas the lights go on they scatter in all directions and loose all there caller. Then added some black rocks in the one corner to test my theory that they do not like the reflecting substrate. Immediately after they go above the dark rocks there color comes back and they look less stressed. Any take on this?

    Cool thanks dudes. Don't want to use florite black seeing no plants going in the subs. I know fish etc. Sold some kind of fine black gravel that would've worked well but they only had tiny little packets of it. So the only thing I can think of is the crushed lava stone.

    So it seems I'll be rebuilding a tank tomorrow because the inhabitants don't like what I have done. :BangHead: But to be honest I don't like it that much to. :ang4:

    If you are looking for a black substrate, I have relatively fine gravel that I took out of my 60CM tank before I put in the AS.
    It is a good few kilos.
    PM me if you would like it.

    They will get used to it in some time, also find that after a big re scape the fish are more skittish and they soon settle down.

    I agree with what you are saying and have experienced that before. But this seems different to me. This tank was the first tank I ever bought and went through a couple of big changes with the same fish in them and they usually settled down within a day ore two. This time not and rite after I added the dark rocks they got color back and seam to hang out there or dart over the white stones to hang out by the darker spiderwood. Strange :scratch: and as soon as the lights go off they are as calm as can be with better color :scratch:

    Wouldn suggest it for inside a tank with fish , as the rock is sharp and many a time when I have medicated the tank the lava rock as reacted to the medicine . Even in the ponds iv seen strange reactions when adding medication.

    white gravel apparently also spooks fish. havent u read in those old books?:p that may be ur problem?

    also another interesting thing with schooling fish is that they will stick to the layout of your tank. if you have 2 peaks, they tend to hover around those 2 peaks that you create.

    looks flipping awesome when you see cardinals swimming from one peak to the other following your trimmed line :)

    Yes men usually favor the twin peaks. :evil6:
    Did not read the old books but did make use of a lot of bandwidth lol. I'm still a newbie and only been keeping fish for almost a year dude.
    Now the funny thing is those old books u read may be rite.

    I got some dark gravel from Darryn and just took apart the whole tank now rescaped it added plants and filled up again using 70% of the existing water. Added some bacteria for good measure and returned fish to the tank. Instant happiness with good color. Absolutely no darting around. Not spooked at all. Immediately started exploring there new environment.
    Or they just hated my scraping skills in the previous attempt. :evil6:
    But now they seem happy so I'm happy :occasion14:
