It would be advisable for you to get some bleach & dichlor and bring up your FC and CYA to normal levels, then turn on the SWCG. As has been noted elsewhere here, SWCG's can't make enough chlorine fast enough to to bring a new pool up to algae prevention levels.

The HTH 6 way would do, until you get your K-2006.

If any of the mods here need to correct me or add more info....
