A natural habitat is an ecological or environmental area where a specific species lives. It is the place in nature that particular species calls home. To help picture what this means, think of a zoo.
Quick Answer. A mixture of vinegar and borax will kill most algae growing on bricks and concrete. Homeowners do not need harsh chemicals to get rid of these pesky growths.
If your pool has this kind of algae, get an algaecide specifically made to eliminate this tough kind of algae. The active ingredient (ammonia or metal) for the algaecide you choose should be at least 30 percent. If it is less than 30 percent, it may not effectively kill all the algae in the swimming pool. After adding the algaecide in your pool, let it stay for at least a day before you do anything to the pool.
