Anyway, tonight I was very busy, but very productive.
Got all my kit delivered today and started some serious work.
First I made sure the tank was in final place and started to fill with tap water treated with dechlorinator.

Once filled I installed my powerhead (a Koralia 2800) inside the tank and my heater in the sump. (Is it okay to have the heater in the sump, or should I keep in in the much larger volume tank?) Hooked up the pump, set my outflow and turned on. Making sure that flows were similar.
Anyway... then I made my HUGE mistake. I turned off the pump to do a bit of tidying up with the boxes I had just unpacked... when I noticed water on the floor. Turning off the pump meant it suddenly reversed flow and became a siphon... I nearly had a heart attack, I live in a block of flats and I could just see water gushing out of my sump all over the floor. I think I lost about 25 litres.
So cue frantic emptying of all my towels and dirty clothes on the lounge, scattered around trying to soak up water. Lesson learned very well. PUMPS WORK BOTH WAYS AND CREATE SIPHONS. At least I hadn't added salt or anything, otheriwse it would have been a major issue, as it was it was just a case of drying everything.
Anyway, after calming down, I cut the pipe from the return pump, so now it is level with the overflow holes. I then glued the pipe to the side of the tank with the rock epoxy I bought... it is not very neat, but is hidden from normal view.

Anyway, a few more minutes of work and salt is added to the water, everything is turned on and the tank is running nicely. Salt is around 0.18 by my refractometer, so I can slowly add more. The flow is very noisy, I need to play around with flow reduction on one of the overflow pipes, but all in all I am very happy with a job well done.
It may not be the prettiest work, but all drilling, pipework, hardware selection, siliconing has been done by myself, with help from a couple of great websites. (Thanks everyone here and at one other forum.)
I have a 25kg bag of sand, 10 kgs of live sand waiting to go in when I find some live rock. So I am now at the point where the first bargain live rock I see will result in a living tank! (I have too much coral sand I think, I bought extra to make a deep sand bed in my sump, but now I have found out that you need silt or mud for that.
Anyway, here are a few pics of it all set up, with the Metal Halide running...

Oh, I forgot one other thing. There is a plastic brace (tranparent) on the tank that can be seen in one of the above pics. Now my halide sits right on top of this, around 3 inches up. Will this obscure the light enough to affect future corals etc?
