You're actually confirming something I've observed at the few LFS
I've visited. Those with a sump system that has a greater volume than their DT generally have few issues. I'm prone to believe now that if ones sump and biological filtration system takes up an equal or more volume of the DT, then chances for diseases and parasites decrease while water quality increase.
This is very important for me because I'm in charge of 3 very large reef aquariums that our company asked for in the design of our offices. While the projects are still in the early stage, I've been preparing a mental concept of how the system will operate. As you know, corporate lobbies are after only the final clean look of a DT and are not interested in what's required to make it work. I'm actually client in this case and want to ensure that the final system delivered is easy on maintenance and provides consistent quality in the DT.
Anyways, I'm off topic now, this may have to be addressed in a separate thread.
