Cheapo alternatives for dry rock or LR?

[SimplyVibing]

I can’t justify spending $10 a pound for LR or $4 a pound for dry rock, AND run the risk of introducing bad hitchhikers into my tank.

Will cinderblocks, lava rock, or pumice stone effectively replace rocks and sand in bare-bottom tanks? I don’t need it to be pretty— this is a breeding setup

It is impossible to get hitchhikers with dry rock. I would not use any of the alternatives you mentioned personally. but to each their own. The best price I know of for decent rock is this stuff. It is not always good looking rock, but it is suitable for reef and saltwater applications. You can get it in 4-8" size as well.

Any local reefers in your area? They usually sell for cheap

Saw a guide here for diy dry rock.

Pumice works wonders as bio media that’s pretty much what pond matrix is.

if it’s just going to be a breeding tank why not just use a slab of marinepure?

Try checking craigslist. Sometimes you can get it for $1 per lb or less from guys breaking down tanks. I always bleach and cure before using though.
