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.
4. Vacuum The Algae OUT. Fill up your pool with fresh water to the very top. Hook up your manual vacuum cleaner (do not use an automatic vacuum for this) and turn your filter to waste, not backwash. Mustard algae can live in your filter, so you donât want to vacuum the algae through your system. Since you are vacuuming the water directly out of your pool, you are going to lose some water. Thatâs why recommend filling your pool up to the top, before you vacuum, to compensate for water loss.
