My Spiralling Lucky Bamboo is turning yellow!

[Guest]

Hello, I purchased 3 stalks of spiralling lucky bamboo about 2 months ago. One of the stalks recently turned yellow at the top where the leaves grow. I just added some more fresh water and waited to see what happened. However, the results were not good, the yellow spread down throughout the whole spiral! When I compared the hardness of the normal green stalk to the yellow stalk it was much more 'squishy'.
I took out all three stalks, dumped the water, washed the rocks, and refilled the water with filtered water form my fridge. Then I washed the roots and put the bamboo back in its vase.
I’m pretty sure the yellow bamboo is a goner, but I was wondering, if I cut off all the dead part (yes I know this means losing the spiral) would my plant survive?
Also, will it grow taller and grow new leaves?
And finally, a second bamboo started to turn yellow just at the tip and the leaves are still green, is there anything I can do to save it?
Thank you for listening

probably the water was salty or has quite an amount of flouride. Before putting the plant in, try leave the water overnight or get some distilled water. Hope it helps
