The runners I am referring to is a new plant growing on a stem with it's own root system and leaves. I could cut it off and it would be a new amazon sword plant.
Yes, this is an inflorescence, with adventitious plants. You can leave them intact (this can be useful to fill in upper spaces), or when the adventitious plants have leaves and white roots an inch or preferably longer you can remove the plant from the inflorescence by pulling it gently downward along the stem. It usually comes off easily. Plant it in the substrate, it will in time attain the size of the parent plant. There will be two separate plants at each node along the inflorescence which will be readily seen if you remove them.
I will look into getting one of the two bulbs you mentioned. I believe the light I have now is ZooMed but I not for sure if it's UltraSun.
There are several tubes in the ZooMed line, as in the Hagen "Glo" line. The two I mentioned are 6500K which is ideal plant light. But one of the others might do, I have used the Tropic Sun which is a lower K and thus "warmer" white. There are some bluish ones with a high K intended for marine tanks and less useful with plants on their own.
It's weird because you all said Cabomba wouldn't grow in light, but at point that was the only plant that grew in my 75 gallon with extremely low light. I looked at one of my old pictures and it was a few inches from the top of my 75 gallon. I lived in a different city so my starting water parameters were different such as hardness and pH. Again thanks for your help it is much appreciated.
You're welcome. You are sure it was Cabomba? This I have found to be high light requiring. But plants, like fish, don't read the literature and may have their own ideas.
