After some rearranging in the sump and removal of a baffle I have it mounted and plumbed in.
It is bigger than I thought and the only way I could make it work was hanging it on the front but it works.
I did use the union pictured above but will probably redo it with the adapters

Here are a few pics. Putting pics of your sump up feels a bit like airing your dirty laundry but we all have them

Probably going to have to move the skimmer over a bit and not too sure I like it in the refugium part of the sump, might need to create a glass partition for it, we'll see if the snails and Bristle worms stay out.
Other than the amount of assembly this feels like a good piece of kit, motor is very heavy, aesthetically pleasing and a seemingly well thought out design, we'll see how often I have to change out rolls before I get too excited but way better than nothing which is what I had as I took the sock section out a long time ago and way better than washing socks.
You know what they say about sometimes it's just the simple things, well this one thing, orienting the plug transformer so it plugs in side by side into my DJ switch with everything else made my day. I hate those sideways plugs so much.
From here time will tell if the expense and work was worth it but so far I am pleased.
time to crack a beer and do a water change now
