AGA Aquariums and MegaFlow Overlflow

[Stones]

I have an AGA 90 gallon with the megaflow overflow. Instead of using the 3/4" bulkhead hole as my return, I use it as my emergency drain line and run a ball valve on the 1" drain to convert the durso system into a herbie style overflow. Works great so far, but just make sure if you are going to do this that the 3/4" drain can handle all the flow from your return pump. The durso was a bit too loud for my liking and now it runs completely silent. So far, I've got nothing bad to say about the tank but its only been up and running now for about 2 months.
