Paul I have the Swc extreme 150 from my old tank if you want to borrow it till your new pump gets here.
It's now stuck in the pit of the USPS system in Kearney NJ. I can't begin to tell you how many items I've purchased that have never come out of the Black hole in Kearney.
I'm now working on some sort of indicator that will let me know when the water bottle is empty. Not sure what I'll be doing....still kicking that one around.
How about a little window like you built on your reactor?
