Lace Rock Question

[LilBabyEmma]

im thinkn about ordering 25 lbs of lace rock. how much would that fill up a 55g tank

 

[mike dunagan]

it is pretty heavy stuff. So I would say it is a start...

Lace rock can be pretty sharp. It also has a ton of little holes that can trap old food and feces. It can be a nitrate trap and damage your fish, especially the eyes. Go for river rock in my opinion.
