Rocks

i found nice pieces of rocks on the side of the road, they are one of those cool looking rocks which you find in mountains. anyway they are little dirty and looks like they some dirt on them, here ad there.

what is the best way to make them safe before i add them in the tank. i was thinking about boiling them for about 1 hour.

is it ok to add bleach in the boiling water?

please let me know if there is any better method but i need a quick method and i have to be sure that i dont kill any fish due to these rocks.

thanks

All I have EVER done is rinse with hot water and drop them in... (Don't really DROP them)

I am leery of boiling rocks, from a personal safety stand point. I would scrub the heck out of them in hot water, then use baking soda on a mostly dry scrub brush. Use the baking soda as an abrasive to get any clinging nastiness off. Make sure you use a scrub brush that is used only for fish things, not something that you have used to clean the bathroom (or anything else). Then rinse, soak in bleach and water for a few hours. Then rinse well, and soak again in a strong mix of water and dechlorinator. Then put them out in the sun to dry for a day or two. That should clean off just about everything. Yes, it may be overkill, and it certainly is not quick...but better safe than sorry. If you were pulling these out of a high mountain stream, I would not suggest so much. But finding them on the side of the road means they have been exposed to all sorts of unknowns...

If rocks had come from a wet location (pond, stream...) then bleach would kill any disease or parasites. Not needed for roadside rocks. Boiling is the same. Good to kill stuff, but I don't know of any fish parasites that thrive on dry rocks.

Roadside = petroleum runoff from the vehicles. I would use a cleanser that is made for washing your hands after working on your car. Scrub a LOT. Rinse well.

Put the rock in a bucket. Let it soak for a few days.
If it is rust, it will look a bit different after being under water. The rusting will be going on, and you may be able to scrub off some, or at least it might smear around when you scrub it.
If it is really rust, but just a little bit, then ignore it, unless your tap water already adds way too much iron to the tank. I have a few spots of rust on several rocks and there are no problems. About 2-3 square inches in a 125 gallon tank. Maybe half a dozen dime sized spots, and a few narrow skeins. I have Bichers, Clown Loaches and a Black Ghost Knife (and other fish) in this tank.

If it is lava, then it will not change when it sits in water, you will not be able to scrub it off or change it, and is usually no problem in a tank.

thanks diana, it seems like today is your posting day lol, i have noticed that today. anyway back to my rocks, i think its rather rust and i will post a picture soon to confirm it from you guys. i was thinking about using that brush with the metal on it instead of plastic. will that take off the rust?

i was also thinking about puting the rocks in oven after washing them in boiling water. will that work for drying them, because we dont see the sun lately, stupid snow.

I agree. Do the yellow spots smell funny at all? It almost looks sulfurous, but the picture isnt sharp enough for me to really see it. Give it a hard scrub with hot water and see what happens. I would start there...

yeah hydrogen sulphide obviously has sulphur in it. Im not sure what the effects of sulphur in a tank would be. Normally this compound has an odor to it. I'd be a little hesitant about this unless somebody else can chime in with experience...
