Hornwort

[$eaba$$]

For some reason, my hornwort is yellowing a bit. I heard that hornwort should be able to toleratre a bit of salt. Right now, I have a 20H and maybe about4 or 5 tablespoons of salt in there in a small cup. I have a 2.5wpg, a 50 watt light fixture I made. I put in about 1 tablespoon of the kent freshwater plant a week, well usually 2 tbs. I will start DIY co2 again. What could be the problem? Also, is it like a stem plant so that I can cut a tall one and just plant the half in?

thanks

Yes, you can cut the stem and replant both sections and both will grow. Why are you using salt? Hornwort often yellows or browns just a bit....do you have any pics?

salt because it is going to be a very lowend brackish tank. i'll try to get some pics. SO it is normal that it's a bit yellow?

I'm not a plant expert so take this FWIW.
My hornwort has a reddish brown color to the actively growing tips. It became obvious when I added more light---all of the apical points starting growing like crazy and turned sort of brownish red (under the green). I'll try to take a pic.

Look at the tips of the plant in this photo. Is this the sort of yellowing you are seeing?

Like mgamer said maybe add ferts....can't hurt just follow the directions. It looks ok to me, my hornwort grows like crazy and has always been slightly off color at the tips.

I think high light also has the effect of turning Hornwort brown at the tips. Yours looks exactly as it does in my tanks, $eaba$$, and it grows as if cellular division is going out of style. Looks healthy to me.

-edit-

I should learn to read. I see now you mentioned it was turning a bit yellow. That I don't know. :\

hornwort is a floating plant, and will not root.
