All, I finally got the threaded multiport off and I am in the process of vacuuming and replacing the sand.

My pool has been full for 10 days now..suprisingly blue. Do I need to add anything to the water while I handle the filter and plumbing for the filter?

I don't want to get algae or any other "stuff" going because I have no chemical in the water.

Regards,

C. Chase
