Right now, keep your pH low (6.8 - 7.2). Using algaecide at this point, instead of chlorine is a good idea, but next year, have the chemicals ready BEFORE you start filling.

Do NOT swim -- you won't be able to control the algae if you start adding people goo. Here's the order of things:

1. Keep the pH low.
2. Add HEDP (don't over dose!)
3. Add polyquat
4. Put CuLator in skimmer, under skimmer sock, OR hang it in front of the return, if you don't have a skimmer.
5. Begin adding chlorine SLOWLY. If you have a skimmer, add it via the skimmer. (Remove the sock and CuLator, while adding!).


Products for metal control and clean-up:

HEDP is a liquid phosphonate that is pretty chlorine stable, and very good at keeping dissolved metals IN the water, instead of ON your pool surfaces. It can lift recent stains, OR it can be used along with ascorbic acid, to keep the metals in the water, after the ascorbic acid is consumed by chlorine.

Using polyquat during metal clean up accomplishes two things: it helps kill or prevent algae, letting you run lower chlorine levels, and it is a very good clarifier, that helps you filter out any small metal particles that may form.(Probably available from pool stores, and possibly some big box stores -- but you MUST learn to ID it correctly. See the polyquat page for more info.)

Ascorbic acid (Vitamin C) can be used to remove copper and iron stains from pool surfaces, and put the metal BACK into your pool water. If you don't have stains yet, you do NOT need ascorbic acid. (Not likely to be available locally, except as Vitamin pills.)

The CuLator product is a special patented plastic material, contained in a bag that goes into the skimmer, that can slowly take metals OUT of your pool water. We think it works, and have some evidence that it does, but not proof yet. (Not likely to be available locally.)
