Several companies call their products "Metal Out", but there are differing ingredients used. HEDP will help keep the iron in the water, so that it can be slowly filtered out. A combination of HEDP, polyquat, and low levels of chlorine can be used to start up with clear water, avoid algae, and gradually remove the iron that's kept 'hidden' in the water by the HEDP.

Virtually all 'Metal Out' like products do NOT get metals "OUT"; they just 'hide' them in the water, by temporarily keeping them in a soluble form. None are fully chlorine resistant, but some chemicals used break down almost instantly when chlorine is added. HEDP is the most effective and chlorine resistant chemical commonly available.

Regardless, you still eventually have to find a way to let the metal go to its insoluble form, and filter it out. the process of
1. Adding HEDP and polyquat as you fill;
2. Running your filter 24/7
3. Continuing to use polyquat for a couple of weeks, while keeping chlorine lower than the Best Guess chart suggests
4. NOT adding additional doses of HEDP, unless you add more water.
5. Gradually raising chlorine and pH levels
tends to filter the iron out, and avoid having so much land on the bottom.


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.)

HEDP is a dissolved phosphonate product 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.

You can also use the Culator product, which will continuously remove small amounts of DISSOLVED (soluble) metals, as they pass over the bag in the skimmer.

The CuLator product is a special patented plastic material, contained in a bag that goes into the skimmer, that slowly removes *dissolved* metals from water passing over the skimmer bag. This approach pretty much requires running your filter 24/7, since the bag ONLY removes metals from water that comes into direct contact with the bag. This product can also help if you fill SLOWLY via the skimmer, so the metals are removed from the incoming water. (Not likely to be available locally.)
