i found these rocks and i was wondering if anyone have a clue what type of rocks these are?

they do look similar to some of the rocks from ADA/ADG. but it would be great if someone can help me with this.
Thanks

i did the acid test, and there was no fizz.
i will see what i can come up with for my shrimp tanks

Nice! Have you done the vinegar test yet?

 

[kamikazi]

looks safe and good to me

 

[TeamTeal]

i havent done the acid test yet, because i have them soaking outside in a bucket.
i will get to that tomorrow in the morning

 

[demonr6]

I think that will be your answer there.. no fizz on vinegar and you should be all good. I am stuck with stupid limestone here in Florida. blah.

 

[mightyoak]

They will look great in a tank! Hope they check out fine for ya.

Looks like a sedimentary rock

The white veins are probably a secondary sediment that would raise hardness in the aquarium. The black area should be safe.
Bottle #1 of API nitrate test kit has hydrochloric acid - drip that on the white veins and if they fizz they will definitely raise hardness, its your call if thats okay with you depending on what livestock you wanna keep.

i will double check on the fizz tomorrow, thanks for the tip

white parts look like quartz to me which won't fiz or effects hardness.

If they are quartz they will be fine, and you're right, they do look like quartz more than anything else.
Any kind of calcium compound wont be good though, seiryu stone for instance has white veins that raise hardness.

good to hear, look forward to seeing these in a tank soon.

i should have rephrased that
i actually did the vinegar test last night and there was no fizz.

However, when i tried the nitrate test bottle #1 today, i saw some fizzing on the white part of the rocks.

Where did you find these rocks if you don't mind me asking...

 

[TeamTeal]

i got them on my way back to the Bay Area from Oregon when school ended. It was around Rouge River

Those are nice rocks. Hope they work for you.

Chlorophile-thanks for the nitrate test kit tip. that's a good one.

I wouldnt worry too much unless you already have hard basic water.

If they didn't fizz with vinegar but did fizz with the nitrate kit, they will only slowly raise your hardness slightly.

Those are nice rocks. Hope they work for you.

Whether or not you decide to use the rocks depends on your stocking plans and your water parameters, and if you are going to be using co2 or aquasoil.
Acidic water via humic acid or carbonic acid (peat/aquasoil and co2, respectively) will make the rocks raise your hardness quicker.
But so does seiryu stone raise hardness, and people use it frequently.

i will have to see what i can come up with. i want to get a bigger ADA setup , but i already have 3 ada tanks in the house and 1 of them is just sitting around collecting dust.

Looks like basalt to me. It's an igneous rock common to the Columbia river area. The white veining might be gunge it picked up as it flowed out of the earth and cooled. This wouldn't persuade me to avoid it.

Also, muriatic acid in the paint section of HD, Lowes, or any hardware store is usually 20% hydrochloric acid. Best bang for the buck for fizz testing and cleaning salt/mineral crust off of aquarium parts (not while in the aquarium obviously (I hope)). Just be aware of the handling procedures when using potent acids (eye protection).
