Hara said:Can you tell me a source on where you heard silica is poisonous? I would be interested in reading this.
Hara said:As far as using crushed coral, that is not a good idea as it will be very hard to control nitrates with that as a substrate. It traps entirely too much detritus.
Actually, I third that. I had a CC substrate and removed it, due to the heavy maint and the limitations on sand sifting critters.melosu58 said:Hara said:As far as using crushed coral, that is not a good idea as it will be very hard to control nitrates with that as a substrate.

My only suggestion would be to repeat what Lisa said here.

i dont have a source, just years of my grandma and mom telling me "keep the silica packets away from your mouth" the ones you get from shoes...
further research revealed for me, that the hazard label was on there because its a choking hazard, not because its poisonous... my bad
in other news... finally my mom was wrong for once
