durso

I don't believe you can call this a "Durso" since his design implemented a downward pointed intake to alleviate the introduction of air. This is an interesting change though since you implemented the surface skimmer which he didn't have to add since his was designed to be inside a surface skimmer.

looks like a good designe. Have you implimented it yet? Does it work well

I have not. I was thinking of trying it on a small cube wasnt sure if it would work or not maybe Ill just give it a go and see.If so it would free up space in small 3 gallon tanks and such instead of having a big overflow box I would think. Any time I touch plumbing its an epic fail though so Im not so sure it will work right lol.

i use a similar design on my 20Long. works great for me.
