    There would be no reason for water level marks on a submersible heater seems to me. What would be the purpose of that? Is this it?

    PS....I have never heard of submersible glass heaters either. It has got to give some sort of directions on the box.

    I have a Marineland glass submersible heater. It has a Min line, but no max line.

    The minimum line is there so that you at least put that much of the heater into the water. You can put it further under water, but not lesser.

    I did find this thread that mentioned some pertinent info that its submersible, but the housing they use is also used in non-submersible types:

    Looks like its confirmed in the comments on the fluvalblog, and they specificially mention submersible in their product video:

    Well, I currently have the same model of heater inside my 100G and i can say that it's fully submersible. They put those "water lines" because of government regulatory as said on another forum..

    I contacted Fluval, and they said it was due to Canada laws, but it is submersible. so I told them they should include proper instructions.
    Da name's Paul. Not Dave. ROFL

    Learn to give and take. That's how things should always work.

    If there was government regulatory on these things, why don't any of my submersible have those lines? I think perhaps there is a difference in submersible than "fully submersible."

    Yes, it goes in the tank in the water but is it supposed to go all the way under water when it states not to? I think if the directions say not to, then I wouldn't.

    These submersibles are all a bit different, I notice. I have one that needs to be straight up and down under water. Another can be placed in any direction. Another when it heats, the light turns red and then back to green and still another it heats when the light is green and then goes to red.

    ARGHHHHHH. Since I get them all mixed up, I just put them all in the corner of my tanks with the dial out of the water. Saves me from having to "remember" which is which.

    I havent had a max water line either...having cheapo tetras that have since been trashed, aquatops(cheap but so far better than tetras), and eheim jagers ( upgraded to two of these, they are nice and have auto shutoff if the water gets too low...they are just huge compared to others heaters of the same watts).

    As Trillianne mentioned they are all built with that same housing that apparently is required for another model or wasn't redesigned for whatever reason.

    It's the same reason that there is braille on the keypads of the ATMs that you must drive to get to. They design and build one kind and use it where ever it fits.
    Gas mileage isn't everything OIIIIIIIO
    Lack of planning on your part does not constitute an emergency on my part.
    Why pretend there are no stupid questions? Actually, There are many stupid questions: "Should I drink this bleach?" Is just one example.
    Having said that, Just because it's a stupid question doesn't mean that it shouldn't be asked. It's better to know.

    A warm beer is better than a cold beer. Because nothing is better than a cold beer, and a warm beer is better than nothing.
