Thanks, Karen for replying to my question. I've got a few more questions on
the method. Is the 7.5 W heater in contact with the bottom of the aquarium -
doesn't there need to be water freely flowing around the heater - any chance
of cracking the glass? Also, I've seen fiberglass screening in hardware
stores, used for window screening. Is there fiberglass screening with a
smaller mesh size........where is this sold? I have seen a fiberglass cloth
in automotive stores, but I would think this would become clogged over time.
Would nylon netting be an acceptable alternative?
