Black moor and algae? fish tank help!!?

Is the tank in direct sunlight? That will make the tank green really fast. Algae is a plant and that sunlight makes it grow and bloom out like crazy. Try putting it in a dark corner of the room and don't leave the light on too long. Algae eaters may be gross to you but they work wonders on a tank. Just make sure its one of the small ones and not a plecostomus. They eat their weigh and more and they never quit working! If you are really against the algae eater, you can try a few of the larger snails instead...they just don't do as good of a job. And make sure you have the right size filter for your tank and try a bit of aquarium salt. Just follow the directions. Good luck!
