Just a quick update.
Some pics of the sump, that took ages to get it under the tank. The plinth will need to be repaired before filling the tank with water.
The rest of the bio-balls will be added later, they are in another tank, so they are already covered in bacteria when the tank is ready.
I love the double rotating arms.
The weir has also been drilled and bulkheads are in.
This is a pic of some of the plumbing, this will be the outlet from the filter, this setup should maximise water flow by pushing the water from the open end of the tank to the weir in the opposite corner, will see if this is enough flow, or if I need another sump outlet. As you can see it is all covered and hidden from view.
I dont think the plinth will be repaired till late in the week, then I will be away at work for the whole next week.
I am hoping to get it set up and filled with water before then, so I can run it for the week I am away.
