The fixture should be fine; chaetomorpha normally does ok under less. I wouldn't bother with a grow light as it does not really add anything other than more expendition. 24/7 is ideal but reverse lighting is fine as well. It is up to you how much electricity you want to burn through. The 24/7 allows for grow and photosynthesis all the time but if you reverse light the water stabilising effects are also captured but costs less.

Hope this helps
