Does a poly pad/filter take calcium or magnesium (supplements) out of
the water. I think i have high phosphates because i use tap water so i
try and put a poly pad/filter in my fluval every now and then to take
all the bad stuff out but i just wasnt sure if the poly pad will also
take out the good stuff. Please let me know or direct me to a link that
may help.

Thanks,
BLONDIE!!
