1. Superchlorinate, brush, and vacuum.

2. Clean the filter.

3. Add a DOUBLE dose of polyquat (http://pool9.net/polyquat/)

4. If you have time, raise your pool's borate level to ~60 ppm. (11 boxes of 20 Mule Team borax + about 2 1/2 gallons of 31% muriatic acid.) See http://pool9.net/ma/

5. If you have someone stopping by your house, you could have them add a 2nd double dose of polyquat mid-way through the period.

Please note that polyquat is the ONLY algaecide that can be double dosed without negative effects.
