This product is an excellent general purpose sequestrant which helps protect plumbing and pool walls from rust, stain and scale. It should be used for all pool openings and closings and throughout the season as needed. For initial filling of pool, if iron or other metallic contaminants are suspected, add one quart of Metal Free for each 10,000 gallons of pool water. Add Metal Free while the pool is being filled and before chlorine is added. To correct an existing colored water problem (due to the presence of minerals in the pool water), first close the pool to all swimmers. Leave the filter pump running. Stop chlorinating the pool and allow the chlorine level to drop to zero. Lower the pH of the pool water to 6.8 with pH Lower, lowering the pH will re-dissolve the metallic impurities. Add one quart of Metal Free per 10,000 gallons of water and allow the pool water to circulate overnight, or until the water is clear. Re-adjust the pH of the pool water between 7.2-7.8 with pH Rise. Begin normal chlorination and pool operation. Swimming may resume when chlorine residual is 1.0-3.0 ppm. To make up for loss of Metal Free due to backwashing and/or splash-out, add one quart of Metal Free for each 20,000 gallons of pool water, once each month.

This product made my pool look brand new. We have well water and therefore, a high amount of copper and iron in the pool. That gives the sides of the pool and even the water a brown tint. It is especially noticeable when you shock a pool. After several years of frustration with the stains, I found Robelle Mineral Out. He tells you to reduce the chlorine to zero and lower the pH. The easiest way to do that, which worked wonders for me, was add regular vitamin C tablets to a skimmer net and hang it in front of a jet. That actually will remove some of the stains, but it only works because it’s lowering the chlorine and pH. After the tablets are fully dissolved and the pool has circulated for a couple of hours, add the Robelle Mineral Out liquid and let it circulate overnight. The next morning the walls of my pool were bright white and the water was crystal clear. I added 3 pounds of baking soda (also in the skimmer net in front of a jet) and half a bottle of liquid chlorine (do not use the shock crystals) and my water is perfectly balanced and crystal clear. This is an amazing product.

While I can say this product did not completely work for me I have unusually heavy iron levels in the groundwater (let in by pool installer)

This product is same in color as Dex all in one which also treats the metals. I live on horrible well water so it doesn't take long to see when something works, and this and Dex both work, but I got 3 of these per one Dex $$. Same color red as Dex, just smells stronger. It does mess with chlorine levels for two days, as it is saps all the chlorine so it's better to now even have any in the pool for a day or two. It turns those aqua marine pools to powder blue after about 15 minutes with pump on. This product is 5 stars because it works and is cheaper then it's clone. However, I also suggest you try hth metal defense for a long term solution as well.

Seemed to work pretty well, still have small speckles in pool. I am not sure if this product or the extra acid I added to pool to bring chlorine to zero did most of the work?

EDIT:It's been 1 year since I purchased this for my pool and the stains have returned. So this product kept them away for 11 months in my 15k gallon pool. I came here to purchase another 2 pack but noticed it's doubled in price since a year ago. I'll look elsewhere for a cheaper alternative even though I like this product.Original review:I was skeptical about this product based on the reviews but I purchased it anyway. My situation was that my in ground pool plaster (diamond brite) was discolored. It was a streaky yellow/orange tint that I couldn't remove with scrubbing and shocking the water. My water is almost always crystal clear so there wasn't any metal discoloration in the water itself, just on the plaster. Mainly the walls and steps. I live in Florida so I have to top off my pool with city water about twice a month and my city water picks up a lot of rust from the iron pipes before it gets to me so I'm sure that's the cause of my pool problem. I have a 15,000 gallon pool so I added 1 container plus half of another and within 24 hours the plaster stain was completely gone. It's now been 2 months since I treated my pool and the stain hasn't returned at all. Not even a little.Tips: Clean your filter before you start. Follow the instructions to a T. Reduce your chlorine to zero. Drop your PH and dump in the required amount of product based on your pool size. Run your pool for the next 48 hours straight and clean the filter again. When I cleaned my filter after the initial 48 hrs hours it went from a white filter to a gray filter and was kind of slimy. I assume this was the metals being removed since I've never seen my filter turn gray before. Now raise your PH to normal range, shock your pool and run your filter overnight and you're done.I think if this product doesn't work for you and you followed all the instructions then maybe you don't have a metal issue in your pool. It could possibly be an algae that doesn't respond to copper or shocking it chlorine. For that you need a different product.I'll update this review after 6 months of using the product and let you know if the stain returned. So far so good.
