I saw this in one of my TFH magazines (tropical Fish Hobbyist) and i was wondering about it. Does anyobyd know how much it is? and anything about it, cuz i looked, but i don't know where to go to find how much it is and all those questions!!
Or look at www.practicalfishkeeping.co.uk (?) - that has an external filter review in there somewhere which is pretty well right I think.
Also look at the article 'fish that fell from favour'
I've seen a eheim tank setup at one of my not so LFS and i think it was running in the 800 dolalr range. Very expensive, awesome tank, but, i would never pay that much. Stick to the tandard 55, you'll be happier that way.
