I would dose heavily with that and try to brush the walls and steps/ladder down as much as possible and the vaccum well. (We even took our steps out and bleached them and the sandbags that go inside to hold them down.) If you don't get the algae under control, you'll never be able to get the PH under control, and that will make it harder to level out your chlorine levels.
You also need to bump up your stablilizer, but be careful not to over stablize because this could cause more algae problems. I would up it by what the bottle says, but then be sure to test it reguarly (morning noon and night) to make sure that the levels are in range and not too high. Good luck!
I would suggest you read through the forum and then go to www.poolsolutions.com and read everything you can on there to see how this forum recommends dealing with problems like algae. You recommened an algeacide and I am wondering what is the active ingredient in it. If it is copper it is DEFINITYLY not a recommended product. If it is sodium bromide or inorganic ammonia compounds then it can create a whole new set of problems. If it is a linear quat it is also not a recommended product. If it is polyquat it is fine to use but only after chlorine itiself has not proved effective.

Also please explain to me how an algae bloom will raise pH?
