I have never had an algae problem like I have had this summer. I finally killed the algae but now I need to vacuum up the dead stuff. I don't know anything about manual pool vacuums so I've been looking on Amazon. There are suction side and pressure side vacuums and don't know which one to get. I know my Polaris is a pressure vacuum but it isn't helping much right now. I keep cleaning the cartridge and lots of white milky stuff comes out but the pool is still very cloudy. I'm thinking that a manual vacuum will help to get more dead algae out of the pool faster so I can see what's on the bottom. I'd like to know more about these things and suggestion about ones that won't break the bank.
