What kind of rocks are these.

[Makavelli02]

When I bought my used 75 it had some rocks with it. I have no idea what the are and if they are safe to put in my tanks. How would I clean them to make sure I don't give my oscars any diseases? These are the rock types.

Seems like lava rock. I have some lava rock in my tank, but I'm still cycling so I can't give you my opinion. Do a Google search for "Lava Rock in Aquarium" or something like that.

There's a test called "the vinegar test". Pour some on the rock and if it bubbles, the rock is unsafe, if not then you're OK.

By the way, you have more than one type of rock. I said it was lava rock, well, pictures 2 and 3 are lava rock, picture 4 is Holey rock, and picture 1 I'm not sure. If you are not familiar with the "Vinegar Test" please take a look at this thread: Rock Vinegar test? [Archive] - Aquarium Forum

Thank you they were already in an aquarium. I am just worried about transferring disease or something that was in the other tank. They have some really dark Algie on them. How would I clean them

Stiff brush, elbow grease and scrub as much as you can off. Then boil or oven at 350. That'll kill anything on then. Just make sure you put them in and let em heat as the pot/oven heats up or they may crack.

Boiling/baking rocks is a very bad idea IMO. I've heard way too may stories of people doing this and the rocks explode because of air pockets inside them. I cleaned some of my rocks in the dishwasher with my driftwood

Humm. I've done a few in my oven and only had it happen the first time when I didn't put them in as it heated up. Lesson learned . He's got porous lava and hidden detritus will not be put down in a DW or just scrubbing it.
