I've just added a fully submersible 100W heater to my 20 gal aquarium. This may be a stupid question but i was wondering:
-if this thing will get hot enough to melt the silicone bonding my tank together? i assume it wouldnt but i felt the heater when it was on and it was pretty dang hot. my tank is homemade and i have the heater set to 76 degrees F
-is it okay to suction the heater to the bottom of the tank where it is partially under the gravel and partially above?
any info would be helpful.
