how to smash LR?

[jaiden]

I have a couple huge hunks of lr which don't look that great (the worst 2 pieces from my hirocks shipment) which I'm thinking of replacing in the display tank. I want to smash them to bits to use as rubble in a future sump. They're about the size of a canteloupe. How can I smash them without powdering them too much or making a huge mess? I was thinkgin maybe wrapping them in towel.. has anyone done this?

I would say wrap them in something and hit it one time and a hammer really hard..Im sure you will shatter some peices that will become mush but one or two good whacks should do it!

Don't forget the eye protection.

If you use a screwdriver or a chisel you can have greater control over how it breaks.

If you can wrap it in some canvas or other heavy material you may save yourself from flying fragments. A towel is not quite enough. The rock is quite sharp and tends to cut material. A few good wacks with a hammer or a small sledge will do the trick. And you'll get some rubble for the sump too .

I was thinking of doing this too. So is it okay if i put the rubble in my canister filter. Would putting a whole rock in the filter instead be better. My canister filter can hold about a few softball size rocks.

A hammer will work but it will "splatter" it more. If you have some kind of chisel or similar it will break muck easier without the "powder"

Hammer and a chisel or flat head screw driver. I have done this many times. I actually frag some large colonies this way
