Ok. I've read (and re-read) every thread about the Ultima II and Bio Wave filters. I'm currently setting up a 675 that will have mostly stingrays.
My question is, which one has better mechanical filtration for stingrays? I'm not worried about the amount of water lost during backwash or the cost, I'm trying to figure out if one is better than the other.
I think I've done too much reading...
