Thanks guys! I don't think I'll have any leaks. Since I discovered the Teflon paste everything I've used it on has been leak free. We will see on Monday.
So far so good the 40 is full and started to drain into the sump. The bulkhead in the sump leaked but a little tightening and it stopped. 180 is about 1/3 full.

That's where the sump pump comes in. Make a giant barrel (or many smaller barrels) of saltwater and use the utility pump to pump the saltwater through the hose(s)
So with the help of Nick we are officially cycling.

I'm still messing with the rock work and will be adding sand but things are underway.
