copper removal filter

Karen,  and anyone else with copper trouble.  Poly-Bio
Marine sells a molecular absorbtion filter that removes
heavy metal from water. That includes copper. It also remove
phosphates, nitrates, organics, pestisides. I don't work
there... Many Mail order Cats. sell it, Called the PMA_1
Fin-l-filter. About $120. The tech at Poly told me the best
flow rate is about 4 gpm. Might be worth a try..
By the way Karen, if your bolbitis is getting out of hand,
wanna sell some?
