The surface water should be agitated (think ocean surface) not still. A marine tank should have water flow of 10x - 20x water capacity per hour. In your main tank the output of all water pumps and power heads should be at least 1500 UK gallons /hour. When you decide to add corals you will probably want to increase that.
Do you get a lot of salt creep on the underside of the wood lid?
Dropping the SG .002 - .004 per day should be fine. I shoot for a drop of .003 per day to go from 1.26 to 1.009 over the course of a week. You need to do the same in reverse after treatment, bringing the SG up slowly.
What are you using to measure the SG?
Keep a close on the pH of the main tank during hypo. There is less buffer in the water and it tends to drop quickly. I keep enough s/w mis on had to do a 10% - 20% daily water change. Of course when I did it I had all my fish in a 30 gallon tank so it was a lot easier to do the water changes. Also, the smaller volume of water allows parameters to change much quicker.
So far so good, I am now at 1.012 and everything still seems to be very happy and eating well, I would say that the fish are in really bad shape though, being absolutely covered in ich and over their eyes as well. Any idea when this cycle will finish (its been about a week now) ?
I dont have any powerheads but I do have three powerfilters with their returns near the surface 2 x eheim 2028 and a 2026 plus the airstones.
I dont get much saltcreep under the lid but I do get it on the lighting tubes etc
This is what I am measuring the SG with :
