    Easiest thing to try is a red light string of 5 watts.
    Just thought you'd like to know that you were absolutely right. The Chaeto is growing very well now. Almost doubled in only a week time! Even though I'm only turning on the lights when I'm at home and not asleep because of the cracked tube. It's cracked, but still doesn't let water in. (I know I know, not smart. I just want to keep the chaeto alive until I get my new - actively cooled - solution arrives.

    I have a reactor that stands in the sump though. The water passing through the reactor just flows over the edge and down the outside again. So, that's not a possibility for me.

    And even if the glass leaked, the lights won't short out because they are on a (usually) isolated power supply.

    Btw, have these been known to crack also? Because, on second thought, this just might be a much better option for me after all...

    Those strip lights don't crack but they go out a lot. At least they are cheap.

    No, I meant the plastic of the external media reactor, wouldn't that crack? Just like the light tunnel of my reactor did?

    I've only heard of those crazing, not cracking.

    Still, even with the more powerful light and the correct spectrum, the chaeto still won't stay alive. I've restarted with fresh batches 5 times now. Meanwhile experimenting with lighting period and flow. But it just turns to snot.

    Any suggestions?

    Since your nutrients are low, try feeding three times as much for a week and see what happens.
