Bad over sight snowballs to big problem

[Jason McK]

hey Tony. There were a few reasons I din
t want to go with a closed loop the biggest being it's only a 40G tank that is going to house mainly LPS and softies. I don't think I will need the flow. Also I would have to drill another hole and I have it too far along to do that. Also the Check Valve I purchased doesn't have a flap. It's a ball type so it's easier to clean.

What else, Matt Rogers @ 3reef.com ran a check valve for many years with out any problems. So he helped convince me it would work.
Everyones suggestions were great and if this even tries to fail I will modify the tank with any of the great suggestions.

I'll post picks when the plumbing is complete.
