Re: Aquatic Plants Digest V1 #90

A thought I have had on undergravel heaters:

Most all aquarium stands are in some sense hollow, either a "hollow"
cabinet or "hollow" cement blocks or....   What if you heat your tank
by putting a heating facility BELOW it instead of IN it.  The
thermostat still goes in the water, but the heat itself comes from
below.  Now the gravel has the best of it (heatwise) and the plants
should do very well????   Dave
