How do you get rid of hard spot algae and keep it from coming back?

I have a lot of hard spot algae, and it showed up about the same time my fish got Ick. How can I keep this from coming back and overtaking my tank again? I've been scraping it off with a metal spatula, but it's still all over my tank furniture....

Update:

The algae is green in color and is noticeable most on the tank glass.

Update 2:

I have an algae eater, but as far as I know, hard spot algae isn't something that they eat.

    Well, it depends upon what size your tank is. If your tank is 10+ gallons then put in an algae eater. They eat all the algae in the tank and it goes away in no time. If the tank is smaller, buy a tank scrubber and wash the inside of the tank.

    I agree with everyone and myself I have a heavily planted angelfish 60g tank that had a terrible algae bloom- I mean green EVERYWHERE- and I added 22 nerite snails, and 50 Amano shrimp, 2 UV sterilizers and within 2 days, my water was crystal and no algae what so ever. Nerites are the best, however they constantly lay eggs in freshwater, they just won't hatch. They are very visible and tacky and you can find about 20 new eggs daily. I also have 4 Siamese algae eaters which are also really good. Take down your photoperiod to about 6 hours a day, cut back on feeding, and you can spot treat the algae with hydrogen peroxide or Seachems Flourish Excel (my favorite) use about 1-2 mL of peroxide or Excel per 10 gallons. So you can squirt 3mL of it on a spot with bad algae and the next day it will be gone.

    Use a metal scraper to get it off the glass, remove the furniture and scrub it before putting back in.

    Get an algae eater 1 per 10 gal (no more)

    Keep the aquarium out of direct sunlight and limit aquarium light usage to between 6 and 8 hours a day.

    Use a siphon hose and vacuum the gravel.

    there isn't much you can do but rub , scrub and clean the tank often. but if you are lucky got to your pet store and see if they have this special cleaning stuff that stops algae from coming back.

    also you can get a "sucker fish" or a "Chinese algae eater" (not sure of there scientific mumbo jumbo but if you ask for them at a pet store they will know trust me.

    p.s you can also get a few snails if they sell them where you live

    they work REALLY good

    Well, all you have to do is get a snail (you can get it by buying plants from a pet store) or get an algae-eater (an Emerald Cory or one of those "wall-clinging" fish). If your snails take over, buy Cichlids to eat them.

    if youre refering to diatom algea, the brown kind that forms in small circular spots, its a lighting issue. dont leave your tank light on all day and night, and limit the light-on time to when youre home and it should help.
