Sprater...welcome to TFP. A good test kit would do wonders to ensure you are hitting shock level. The TF100 from TFtestkits.net or the Taylor k2006 is also good.
It takes a sand filter much longer to filter out algae...I would plan on 5-7 days at shock level, based on that visual....time to hit wally's for their 1.42 gal Great Value 6% household unscented bleach
