Jonathan F. Posted September 9, 2009 Report Share Posted September 9, 2009 Hi all I am looking for lava rock for cps but I can not find lava rock only lava lumps from a fish shop and lava rock for BBQ? Quote Link to comment Share on other sites More sharing options...
Amori Posted September 10, 2009 Report Share Posted September 10, 2009 (edited) I use Lava lumps from fish shops, which I break into smaller chunks (nice coarse pieces ranging from 3-20mm). I use it in my experimental inorganic Heli and Nep mix with rockwool and perlite with no negative results to date.
