Opinions of AGA Mega-Flow Overflow Tanks

Is it? We didn't get the kit with the 120's--just the overflows. Good to know. For the water coming into the sump, have the return come out under the usual water level with a small hole drilled a few inches above the water line for air to escape. Prevents the splashing noise, and keeps air from creating a back up in the pipe.
 
I was pleasantly surprised to see that they were using a durso standpipe. With the added bonus that it's adjustable for your water level.

Now that the tank is full of saltwater, I am seeing new flaws in my sump design, but that's another thread. At least there's time while the tank cycles.
