re. decking treatments

Algae tends to thrive on a rough or porous surface, especially with
trees overhanging.
The ones I mentioned both form a thin surface film which discourages
algae by making the surface less porous.
They protect the wood from weathering better, and last longer but
need timely maintenance .
The non film forming ones usually have fungicide/algaecide to help
stop algae, and are more forgiving of neglect.
In view of the fact the deck is 10 years old it might be worth giving
the latter type a try.
If the results aren't satisfactory then let it weather off and try the
former type.
Thanks, Pete.
