This is my first post so please forgive me if this is not the place to ask this question or if it has been answered and I just could not find it. I am wondering if anyone can tell me if a tank is drilled for a 16" Synergy reef shadow overflow are there any others that will fit? I am planning on getting a SC aquariums 150 gallon tank drilled for the synergy reef overflow. After doing more research I don't think I want a synergy reef overflow. I also don't want there tank with the built in overflow and don't want to drill my own holes. Any thought and help would be much appreciated.
