Any thoughts on fighting algae growth on Kool-Dek Surface?

[mneal]

I have had a constant battle with algae growth on my pool deck surface (Kool-Dek) since pool was installed about 2.5 yrs ago. I was if anyone had any input on how to fight the battle? I have one area where the deck has a low spot and it puddles which obviously does not help, but there is also other areas of the deck with problems that have a proper slope still grows algae quickly. (pool deck is shaded alot of the day and that is root cause I am sure) I am tired of bleaching/pressure washing every 2-3 months. I know they make sealers but not sure if they would help and I fear they might yellowing/peeling etc. , not sure about durability of the sealed surface. Anyone have any advice?
For the low areas I thought about making a ~5" diameter hole in the deck, removing some fill, back filling with stones and adding a deck drain to the low spot. Might look sorta goofy not centered etc., but might look better then a puddle.

Pour some bleach on the areas that get algae when it starts and then brush them. If it's easer you can put the bleach in a spray bottle so you can spray the areas when you see algae starting.

You could punch a much smaller hole at the lowest point of the puddle. 3/8ths might do it. The ground below will absorb a certain amount of water. How much depends on what's down there and how much water is accumulating. It should at least reduce the problem, with out getting too radical on your new deck. 3/8ths would be far too small to be a tripping hazard, and wouldn't be as obvious. It might clog , but if you had something to ream it out with occasionally that would help.

Rule of thumb with decks, start small, and then expand from there. Last thing you want to do is create a bigger then needed void and/or eyesore.

Then if you think it's reducing the problem but just not robust enough, cut your 5" hole, excavate for stone, and mount a grate/drain.
