Found a lava rock at school today..

[deeleywoman]

for the record, i lived in central florida for two years and never once did i tan. >.>

isn't there a way to seal rocks and things so that they don't leach harmful stuff into tank water?

This may sound dumb but how did a lava rock get to AZ ?i found some rocks here in MI that looked like lava rocks i did the vinegar test and they sounded like rice crispys found out later it was slag from a foundry

With the San Andreas fault being right there it doesn't really surprise me. It could have easily been spewed up during an earthquake years ago. Lava rock doesn't necessarily have to come out of a volcano it can come up through the fault lines as well.

i did the vinegar test and no bubbles

it just dripped right off..

im assuming thats a good thing, and its ok for the tank.

We have lava rock all over So Cal, they use it instead of grass in alot of dry places. Nothing like a row of rock lawns,

To be honest, I really dont know. I go to ASU, and on the campus they have this landscaping portion that has nothing but a ton of rocks. It caught my eye because it was really porous and holey.. so I scooped it up and noticed that yeah, its a lava rock. Guna try that vinegar test today though.

I washed it off with our pressure washer only because some of the dirt was hard to get off.. the pressure washer took care of that though. Lol:headbang2:
