You've been really busy. Thanks for sharing. ( I edited your entry so the images would show up)

Have you tried to simulate a power outage to make sure it doesn't drain more than the sump can hold? I like the baffles system you came up with, and the fact that you used the lid to make sure the sump retained its proper shape.

Your build is looking good. As you mentioned you went with the bean animal drain set up. On the second syphon drain there should be a fitting on top of the cap with a small air tube to allow for air suction. Bend the tube into the overflow box just above the water level. If first syphon ever fails then once the water level hits the air tube it will turn that drain I to a full syphon. I also used this setup on my 60 gallon cube.

Thanks. Yea, i tested for all the fail situations i could think of. I also am using a ratchet strap around the middle of the tote to help it keep the shape.

Yea so far i have forgone the extra siphon on the backup because i didn't have an easy idea of how to keep the airline at water level. but i can always add to it later.

What i'm noticing my biggest problem is that my return pump is more under-powered than i calculated for. i think it is because of the one way valve and the T are restricting flow. for now i think its good, but i have been thinking that a scwd would be a good addition in place of that improvised Y

I will post a pic of how I did mine probably tomorrow. I made a cover to sit on my over flow out of acrylic, used a Johnny quest fitting in acrylic, ran tube from the cap to the fitting the a straight shot to the water

Great job, your build looks promising. One suggestion: in one of your pictures, behind your sump, I noticed your electrical output with 2 cords plugged in. If possible, change those so the cords each have a drip loop. Make sure to keep posting with your progress!
