whats your opinion on that? Is it controlable? Does it harm livesand?

thanks

i dont think its a good idea....most like pointless. theres absolutely no flow whatsoever in the substrate it would be really hard for the heat to travel through the sand and into aquarium water. if anything i might cook the bacteria in the sand long before it heats your tank.

Sounds like something interesting... I say try it.. on a different tank. HAha

Unneccessary. Just get a visitherm stealth.
