I am totaly puzzled on this one/
I have been using plain ole aquarium sand/aragonite in my deltec reactor for years.
And for all of those years it will always churn the media very well. Totally fluidize it.
Well today I just decided to try out some medium grain ARM and for some reason I can not figure out it just will not move the sand. I took the whole thing apart like four times now.
I cleaned the pump, even put on a spare I have. I also took nearly all of the media out leaving just a couple inches in there and still no motion.
It's like the sand is restricting it so much that it wont break apart and fluidize. I have had my reactor almost full of sand and it churned like crazy.
Any idea or anyone know some things about arm that I am missing?
Is there something about arm that makes it dense or heavier than "normal sand"
This really just makes no sense to me at all?
