heater question!

  • We are currently upgrading MFK. thanks! -neo
It won't work very well without water moving around it.
 
it wouldn't be bad for the heater, but the gravel would stop it from heating the tank (pointless):screwy:
 
They make cable style undergravel heaters if your looking to hide it....or just go with a nice in line unit thats out of the tank entirly...
