There are pros and cons to LRT's but the nice thing about them is the flexibility they afford.
Just because you have them doesn't mean you have to fill them.
We have them in our 150-150 (42 gallons total) and they have spoiled me rotten.....to the core rotten.
Ask anyone who has them (TD and Geoff first come to mind) and I believe they'll tell you the same thing.
