Restoring/maintaining hardwood decking - advice please.

I have a yellow Balau deck just over 4m x 4m. Every spring i pressure wash and oil using something like Ronseal clear deck oil and it looks lovely for a few weeks before going silver and then covered in algae (it is north-east facing). Having done a bit of research I suspect I may not have left it long enough to dry prior to re-oiling. But I also think the Ronseal stuff isnt much good.

I would like to try and restore it before re-oiling. It has quite a bit of mildew and some silvering/fading but it looks lovely when wet. I have seen a product called Net-Trol. I would love to hear from anyone who has used it to restore the colour of hardwood decking, whether it is any good or not, or any similar product that works well. I have also seen suggestions of using bleach to remove mildew but I worry that it would bleach the colour of the wood - I want it to look darker not lighter!

Then I want to give it a couple of coats of a really good oil with UV protection. I dont want to use Ronseal or Cuprinol having had poor results so I am looking for something that lives up to the hype. Maybe Manns or Osmo? I have been looking at Owatrol but at £567 for 20 liters I cant afford to do that every spring! (the web site calculator says I need 18 liters).
