Re: [GSAS-Member] Daphnia in Season

[Steev Ward <steevward@yahoo.com>]

"Metaframe" is a slang expression referring to the old tanks that consisted of 
metal
frames with the glass glued in with a kind of tar. Metaframe made a lot of 
them. Some
of them had slate bottoms. An interesting note is that the Metaframe company 
was one of
the first if not THE first to mass produce the "all glass" tanks that we use 
today,
which are glued together with silicon sealant. I think they started that in the 
early
70s. THEN a Metaframe tank meant an all glass tank with a plastic rim around 
the top
and bottom.

Hydra bad. But they can be dealt with. One good way to get the Hydra to a 
reasonable
level is to pour the Daphnia into a new bucket each day, because the Hydra like 
to
stick to the sides. The Hydra are there BECAUSE there is lots of Daphnia to eat.
Otherwise their numbers go way down.
