			 use a stockman instead of a durso-takes up less room with the same results.you also might add more inlets to the main floor tank.you can do this by using a 45 into a t ,then branch them out.i've used this on my frag tanks with great success

			 also for upstair, i will use Hofer Gurgle Buster instead of durso.  
		
	
		
		
		
		
			So other than not to plump the drain from upstair tank into of basement tank, everything is good?

			 Yeah it looks good.  I definitely wouldn't tie the two drain lines together  before they enter the sump as previously mentioned.  I would have separate drains straight to the sump.  I also prefer at least two drains per tank for backup so I would want another one on your main tank, but if everything is dry walled you might have to live with what you have.

			 But the tank downstairs isn't plumbed to the drain from upstairs yet right? if no, run a seperate line.

			 Do NOT rely on check valves at all!!!!  They will cet encrusted with worms or algae and will not seal when you need them.  Been there, Had that!   A look inside any pipe thats had flow in it for 1+ years reveals all sorts.

			 Have you seen the size of this guy's sump? I doubt he needs to rely on check valves but they are nice to have.
