Undergravel Heaters

Sound the alarm!!

Flack jackets at the ready!!


:lol:

Seriously though, if you want to heat your tank, they're fine. If you want to help your plants an undergravel heater will have no effect. Expensive bit of plastic coated wire essentially ;)
 
I've used one for the last 10 years or so, but mainly because it's what I started with!
As to any Benefits i'm not really sure but they must help drawing nutrients down into the substrate for the plants roots as well as making the substrate a Biological filter with a Huge surface area!

If you've got one kicking about theres no harm in using it. Just don't expect it to do anything magical with regards to anything but heating your aquarium :) It could also be a nightmare to remove if it failed (though I guess you could just leave it in and use a different heater if that were to happen).
