I've been watching the BRS WWC you tube videos. WWC mentioned they feel part of their success is using taller tanks. I'm having a custom tank built and was going with 24" high. However, after watching these videos I'm reconsidering. I went to the LFS and looked at a 30" high tank and thought it was too tall. I've had a 300DD in the past and 27" wasn't too bad. The new tank will be SPS dominated and lit by 2 Radion XR30 Gen 4 Pro's mounted in an Aquatic Life t5 Hybrid fixture. The new tank will be 60" wide and 30" deep. I'm interested to hear what others have to say on this topic.
