Another New Aquarium Question

Once I settle on an aquarium, I'd like to add some Shale and Lava rocks
from our local area to create a nice looking setting and to provide some
'hiding' space for any fish wanting to do so. I know that this not
recommended due to possible contamination issues. HOWEVER - if these
items were soaked in say a 5% or 10% solution of bleach, then thoroughly
soaked & rinsed, would they likely be OK from contaminates and perhaps
minerals(?), or should I simply bite the bullet and pay a heavy price
for features from my local fish store? I'll use whatever gravel comes
with the set up and would really like to make it look nice inside,
however the safety of my little finned friends is more important than
the use of local rocks.

Thoughts, comments, absolutes?

IMHO, I would just boil your rocks for about 30 minutes. Botulinum, the
bacteria which causes botulism lives adundantly in common dirt. It takes
roughly 20 minutes to kill the bacteria, so you could do 30 just for good
measure if you want. If the rocks are two big, you can bake them at 300
degrees for an hour. Does the same thing.

That'd work for me. These are no more than 6" max dia, probably closer
to 4" - the pieces of lava rock.

Also, I wouldn't recomend shale as it composed of clay and sometimes can
release petroleum into the water. Lava rocks work great. Limestone also
great. Holey Rock, which is limestone, is also a great option and really
cheap on ebay. It might raise your pH a tiny bit, but you can monitor that
pretty easily.

Ahhh, didn't think of that with the Shale. I liked it because it was
fairly thin and would make a nice platform on top of the lava as well as
a somewhat secure hiding place for the fish. Maybe we have some
limestone or sandstone around locally I can use. If not I'll likely buy
at a store. I was going to use some "Desert Rose" (Gypsum) but found
it'd likely fall apart in water over time sooo...

We have some really nice red & black granite here too and I'd thought of
using it as the gravel as it would look nice, then remembered all the
work required to crush it. Plus I had a concern with the sharp edges.
Rocks & minerals are another of my hobbies and I'm a novice at it too.

I use rocks from the yard and woods with no problems at all. Just don't use
porous rocks from agricultural areas where toxic sprays or spills could have
occurred. Shale is not porous so should be safe. No need to spend a bundle
at the pet shop for rocks.

HOWEVER - if these
items were soaked in say a 5% or 10% solution of bleach, then thoroughly

Bleach wouldn't stop minerals from leeching from a rock that leeches.
Bleach (the chlorine in it) is only a disinfectant. It kills bacteria and
viruses.

or should I simply bite the bullet and pay a heavy price
for features from my local fish store? I'll use whatever gravel comes

Then skip the horrid red, blue and other unnatural looking gravels. Stick to
natural colors.

however the safety of my little finned friends is more important than the
use of local rocks.

If you plan to keep fish that do better in acid or neutral water skip the
limestone rocks.

=====================
This really surprised me as just about every pet shop sells shale. I've used
ir for years and never was aware of any problems.

I buy all my aquarium gravel at Lowe's. You can get a 50lb bag of natural
brown gravel for less than $4. :-) They also sell bags of other natural
stone and rock that looks great in an aquarium. It needs little rinsing
before use.

Are you sure it isn't slate? They look pretty similar as they're
geologically related. I do better with pictures so I thought I'd share
one that has a slate plate (lol) in the tank.

Nope. It doesn't look like that at all. It's thinner and comes in what
looks like flakes with sometimes sharp edges. That looks like the limestone
we have right here on my property.

Hi Jeff, I never thought of the landscaping places. Good lead, thanks!
I went to our local fish store this AM to get crickets for our
little toad and snooped at aquariums etc. I noted they had all manner
of different rocks, starting at $2.99/lb for the same lava rocks I
picked up for free along the roadG.

I'm wondering if the pieces I got are slate instead of shale. Have to
look closer at my books. Whatever it is it's flat, dark gray in color
and splits fairly easily lengthwise. You can see the grain lines
running lengthwise. As time passes I'll learn a lot more about rocks
and fish both and do a much better job of describing and IDing them.

Hi John,

Nice to meet a fellow rock fan as well! You could also find a nice flat
slab of marble or slate, shale's harder cousin. Do you have any landscape
supply shops near by? They usually sell in bulk to home builders and pool
builders, but it's been my experience they'll let you have a dozen rocks for
around 10 bucks.

Does it require any special cleaning? I was under the impression that
their rock was treated somehow. If not that'd be great as I have a
Lowe's real close by. I'll have to give them a look see for this stuff,
thanks a bunch!

Other than the color, it looks the same as in your pic. Mine is dark
gray and extremely dense. It looks more like solid rock as opposed to a
sandstone sort of look. It's rather heavy too. Time to hit the books
to better ID it.

Sandstonme is a good stone to use as well. We do not have any stones
in this area, and all are imported from the north end of the state or
out of state. I never fail to stop and pick up a rock no matter where
its at if I see it laying there. Rocks area a premium so I sure do
not let them lay. I normally rtinse my rocks I find, and then treat em
with a dip of Potassium Permanganate or common househood bleach
(chlorox) rinse well and allow to air dry in the sun. Within 24 to 48
hours all traces of chlorox will have dissapated since air and sun
make it inert in short order, and they are good to go. I have slate,
shale and sandstone and in some tanks also use limestone. Limestone
will alter or can alter ph. Use white vinegar and drop some on rocks
your not sure of iand if it fizzies its linestone based. I know my
cichlids certainly would be disturbed if I took out my slate and shale
rock wall that literally covers the entire back of a 75 gal
tank.........never had any film come off any rock after I washed them
properly.....not saying it can't happen, but I have never seen it.
