Hi, I'm a first time pool owner. Two weeks ago I opened my pool (21' round that came with the home I bought last winter), and with some help was able to get it up and running. It ran fine for about a week until I started getting a lot of water leakage out of the waste line, while the multivalve was set to filter. Long story short, turned out I had to buy an all new sand filter with multivalve. Because it has been raining all day today, and forecasted to rain all week, I've decided not to set up the new filter until after the holiday weekend, which I will be away for anyways.

Is there something I can do to keep the water from turning green or whatever else can happen to it without running the pump and filter for a week? Chlorine tablet in that floating basket possibly?

Thanks
