They are just sitting there looking at me after a month. I noticed the plants 
in the water like java fern, riccia, and java moss and especially algae, show 
good growth. Rooted plants are declining or stagnant. Some swords are sending 
plantlets into the water. Plants  on the bottom like baby tears and glosso 
rotted away but some pieces torn loose by the fish are alive and well 
floating at the surface.

My tanks are in a cool (unheated) basement. I'm going to insulate the tanks 
and add glass tops. Evaporation is 1/2 inch a day.
