Why vaccinate adults against hepatitis B? Hepatitis B can lead to cirrhosis, liver cancer and death. Hepatitis B is incurable. Up to 1.4 million Americans have chronic HBV infection. Hepatitis B is 50 to 100 times more infectious than HIV.
Re: Pool about to overflow from heavy rain dunno of this works, but try this: put one end of a hose in the pool, the other in a lower part of the garden. Now you need to suck on the hose (the side outside the pool) untill water starts running, normaly, the water will drain.
1 Run your filter 24 hours a day and backwash 3 or 4 times a day for quickest results. 2  Green or cloudy water will quickly clog a filter, therefore you may have to backwash your filter many times a day until the pool clears. 3  THIS IS NORMAL 4  ! Remember, you cannot over-backwash a pool filter. The pool will never clear up if the filter is not working properly 2  ! Once the water does clear up, you will most probably see debris on the pool floor (dead leaves, algae, etc.). 3  If there is only a small amount of debris present, you may want to vacuum it up using your own pool vacuum system.
