I usually only use tank water on it in the Summer when it is sitting outside on my front steps. This is the first time I continued into the Winter, it's blooming season. And I think it was a mistake to do so. It grew great leaves, so heavy they are now all flopped over. But only 2 spikes, 4 flowers. Far less than in previous years. I think the high nitrate inhibited the flowering. But what flowers they are! Almost orchid-like. And the plant is HUGE. That's a 14" pot it is in, and a Queen size bed it is on. The longest leaves are about 2.5 feet.
It now has 11 mature offshoots and several smaller ones. It has never been divided. My goal was a large specimen plant. I've owned since it was a single 2" bulb. It is about 20 years old now.
