My tank is setup as follows:

Hydor Koralia #2 ( I do agree with you, i dont find that this gives enough water flow )

i have one of these in a 25 g tall. 24w x 24t x not sure deep. i am setting up and once it has cycled i will be adding at least a koralia 1 to up the flow. so cant see this being enough byitself in that tank.

That looks like a Visitherm Stealth Heater which according to my LFS is the only aquarium heater to be CSA approved as fully submersible. It has the CSA logo on the box and the box says "Fully Submersible". It's all plastic and does not have an "on" light, I really like mine. My tank is always 78*. Anyone use this heater?

It is that heater and it seems to work pretty well. The nem is opening up a bit and it looks a bit better. Maybe it just got cranky?

Many heaters have the fully submersible rating and CSA approval. People have become ill consuming federally inspected produce. Matter of choice I guess, I choose to keep the top of my heater above the water line. The adjustment knob is a mechanical interface to the internals of the heater and I just don't feel comfortable having that under water. I do have a small powerhead running my skimmer which has the cord partially submerged, so I guess I'm taking a chance there, but those are encased in epoxy and there isn't the mechanical interface I mentioned as in the heater.
