Hornwort in your tank?

[Kaneu]

Does anyone have hornwort in there tank? Is it worth keeping? I know it can grow extremely fast and can be a pain to have to constantly have to trim it down.

I also read that it can't be planted in the substrate? Is this correct?
What are your thoughts on this plant?

Thanks in advance

I have grown this. Fast under good light, slow under low light. I had it planted in gravel or soil and was fine. Too much iron dosing tended to brown off new growth I noticed.

I wouldn't grow it now in the CO2 injected tank as I'd be trimming it too much and trying to get away from that.

I won't be injecting co2 in my tank. Just doseing with flourish Excel. So hopefully that will be good.
