Re:surface extractor

I use a Wasseroberflachenabzug or Taunus (it's German and I think that that 
is the name!!!! ) surface extractor that is self adjusting to cope with 
varying water levels.  It gurgles,  but I have never had a fish sucked 
thru.  It has a sliding two piece tube design and the top tube has a grate 
and a ring to trap air to keep it floating.  As the level drops, the top 
tube just slides further into the bottom tube.  Has about 4" of travel and 
that should take care of varying water levels between water changes/top 
ups.  Blue and white box, but cost 2 right arms and half a  leg!
