Have a friend with an inground pool. Every year they uncover the pool and it looks good but is green before you know it since they fill with well water. I thought maybe to get the water up to a shock level before they start adding well water might help. Is there a better way? They use chlorine from the pool store, I think.
Using well water to fill

Welcome to TFP
Usually, the biggest concern with well water is iron (Fe). Sometimes the water in pools filled with well water containing iron will turn green when chlorine is first added and this can be mistaken for algae. The green on a freshly-filled well water pool should go away in a day or two. If not, you can use metal sequestrant to deal with the iron. Note that sequestrants do not remove the iron. Instead, it binds to the metals and prevents them from depositing as stains. Since sequestrants slowly break down in the pool, periodic additions are necessary to maintain the correct level.

Do you know what type of chlorine this is? If it's from a pool store, it is likely one of the following: trichlor pucks, dichlor, cal-hypo, or any of these that are combined with an algaecide.lbcornett said:
There's a ton of threads about this if you use the search feature.
Iron is the biggest problem. Well, you'll be able to read about it if you try the link. I'll stop typing now.

They're pretty sure it's algae but I'll suggest that it could be iron and I'll let them go from there. No idea what kind of chlorine they've been using. I've tried for a couple of years now to get them to switch over to "our" way of thinking and finally today they asked on their own about it. Maybe new converts on the way! Thanks for the threads on iron Richard.
