Re: Surface Extractors
Several people have offered their designs for a surface extractor.
These seem to have several element in common. However, they all lack
a couple of features that the Eheim Surface Extractor has: (1) The
ability to take the water in from both the top and the bottom. This
minimizes the surface water movement to reduce CO2 loss. Also, when
the top slits are blocked, e.g., with leaves, the bottom intake should
open up more (automatically) to compensate, and (2) The ability to
easily shut off the surface skimming action temporarily (for feeding
purposes).
From a past message, I think Ivo's design handles item (1). I don't
know if it does item (2) also. I'm interested in knowing if the Taunus
design also does these two thing.
As I have said, the Eheim extractor isn't perfect, but it has it's
advantages.
Hoa, still looking for the perfect skimmer.
