Lava rocks in an aquarium?

[Sea-agg09]

Can you do it? Any ill effect that anyone has dealt with or know of?

Ive never done it personally but I dont see any problem with it I've seen a couple tanks that use lave rocks covered in Christmas moss

I've read a bit and apparently they just need to be washed really well. I scrubbed the crap out of them and soaked them in chlorinated tap water, baked them to dry them thoroughly and sanitize them, and washed them again.

I have used them since my early days of fish keeping.....just rinse them with hot water real good and your good to go.....some folks, myself included, use the smaller lava rocks inside their canister filters.

Ive been using a type of black lava rock in my tank for years. Have never had any trouble at all. I do find that the unique texture of the rocks makes them easy to stack and make some really cool caves.

Sorry to revive this thread but I was wondering About where I could get large lava ricks for my 85g

try landscape yards...call around and ask them.....I came from SoCal...back in the eighties...I used to just drive up to the high desert (about 60 miles) and pick up all kinds of nice pieces of lava rock and other nice pieces of decor....manzanita brush is native there too....smiles.

Thanks for the tip, I had considered it but I wasnt certain if those places would have rocks suitable for aquarium use. I suppose if you wash them they would be fine?
