Recently bought a trigon 190 set up. Set up as per instruction added water and added nutrafin water conditioner (250ml) as it said approx 25 ML per 40l. I now have a scum type layer on top of the surface. I have been waiting for it to clear, 2 days but as yet still there, it's not quite a foam. There are no fish in yet as I wait for the water/tank to settle and I have been holding off on swapping out 30% of water as some people say just leave it. Help please so I don't endanger any fish. No danger yet but want to make sure I get everything off to the best possible start.

Thanks in advance, Craig

Have you cycled your tank? You need to do this really before adding fish. See here.

Specifically this bit
 
With regards the scum, try scooping it off with a jug. Get rid of as much as possible, and see if it returns. It could be just that you didn't clean the tank or decor well enough, and it's a layer of dust.

It's quite an old article, and needs rewriting, so I'd suggest you follow the Add & Wait method.

If you can be patient now you will be rewarded with a healthy tank that, if looked after will give you a long time of pleasure.

I'd go with the fishless cycle since you havent been ensnared in getting any fish yet. If you had two fish in which one went through a fish cycle and the other one was added in after the fishless cycle, the second fish would live a longer and healthier life than the first ((if the fish didn't die during the cycle)).
 
You'll want to get your hands on a liquid test kit for NH3/NO2/NO3 as these chemicals will tell you when your cycle is over and if your fish are in danger of poisoning from them. A bottle of household ammonia with a few drops or so will start the cycle.
 
Good luck!
