Best mushroom rubble

[silviaman12]

I have a basket of free floaters right now, what does everyone use for a substrate to make them happy? I've had them in low flow with rubble for weeks but I'm wondering if the pieces may be too large to foot onto? Any help appreciated!

I would think any rubble would work. Some people use calcium reactor media.

marco has some good bagged rubble or you could just smash some rock you have and make it yourself

I use this.

U can also try seachem matrix, it's sold as a bio media but I have seen people used that

Smash up some rocks or use frag plugs. If the frag plugs are too tall, remove the plugs and use the disks but save the plugs to remount.
