| I don't know why you want to bury the heater but if you want, there are two ways which I know. I used both for Dutch Aquarium (Planted Tank).
One is Heating Coils w/ External Temp Controller (Dupla used to make them but i dont know if still available in US). This system is pretty expensive.
Another method i tried was Heating Mat used for Vivarium which goes underneath the tank. You maybe able to buy preset mat (cheapest) or one with separate temp controller (controllers are always expensive).
Like I said, Dont know what exactly you are trying to achieve but hope this helped. |
