A Day without Immigrants

As you may of heard today February 16th, 2017 is a day of protest across the nation. Being referred to as the “Day without Immigrants”, the protest is in response to policies and rhetoric of the current Administration that have been construed by many as anti-immigrant.

United Chemical as an organization does not take a political position. Our people come from a variety walks of life and political affiliations. I would never impose my personal political beliefs on members of our company. However, we do support our people. And the majority of those that work here at United Chemical are immigrants or are the children of immigrants.

We have discussed it as a group, put it up to a vote, and have concluded as a group to close today in a sign of solidarity for the protests and immigrants. While we all here may have different political views – even sometimes at odds with each other – we still support one another as people.

Both the office and production are currently closed. Our normal hours will resume tomorrow February 17th, 2017. This decision was not made lightly, and we apologize for any inconvenience this may cause. While you may not agree with our decision, we hope you support our people for taking a stand for something that they believe in.

Thanks for your understanding and support,

Secrets to Removing Stains

While there are a number of frustrating problems a pool can present you with, few are more difficult to deal with than stains. Here are the secrets to removing stains and keep them from coming back!

What Are Stains?
Stains for the most part are metals. All pools contain a certain amount of metals (from dust, rain, swimmers, etc.). The metals in pool water will become insoluble – meaning the water can no longer hold them. These metals end up falling out of the water and form a stain on your pool surface. The metals will form a chemical bond with the surface so they can’t simply be brushed away.

How Do I Identify a Type of Stain?

Since 99% of the stains are from metals, and most of the above mentioned chemicals will work on any type of metal, you don’t really need to worry what kind of metal it is. However, we have provided a guide to identifying what type of metal a stain is. Realize though that this is not absolute since a particular metal can form a stain in a variety of colors.


Colors of Stains ( most frequent to rare) 


  1. Black – Manganese
  2. Grey – Silver
  3.  Brown – Iron
  4.  Blue/Blue Green – Copper   


Why Do Metals Stain Occur?
There can be a number of reasons why metals become insoluble. However, it is always a result of the metals reacting with something to form a compound water can dissolve. The most common things they will react to are carbonates, which are in most pH and alkalinity raisers (we have Easy pH – which does NOT contain carbonates to prevent staining) and is what alkalinity measures.
Other things that cause metals to become insoluble are things like shocking (adding large amounts of chlorine), water becoming super-saturated (meaning that there’s more metal in the pool than the water can dissolve), or simply adding chemicals that contain very reactive metals (like silver and copper algaecide).

Can I Get Rid Of Metals?
The short answer is no. While there are products on the market that can significantly reduce metal content which does lower the likelihood of staining (such as our Metal Treat), you can’t have a “metal free” pool. The reason is for most pools, metals are constantly introduced to the water – mostly through dust. The most you can do is balance the pool correctly to prevent stains, and add products that will help remove some of the metal content.
Often we’ll get calls from people who have stains, yet when tested show no signs of metals. This is because of two reasons: 1. The metals have already fallen out of the water to form stains – thus not showing on tests, and 2. Tests are limited to certain kinds of reactions, and there are infinite types of metal containing compounds that can be in your pool.

How to Remove a Stain
Since a stain is a metal that is insoluble, the secret is to make it soluble again. A stain remover will need to react to the metal to form something that water can dissolve again.
You could classify all stain removers into to categories – an oxidizer or a reducing agent. Those are fancy chemistry terms to describe how the metal will react to a chemical.
An oxidizer will react with a stain to give it an oxygen molecule; think of it as attaching a handle to the stain so the water can grab it better. The stain is then lifted back into the water where the water can get a better “grip” on it.
A reducing agent does the absolute opposite of an oxidizer with the same results. A reducing agent takes away an oxygen molecule, thus breaking the bond the metal has with the pool surface. The metal can now be dissolved back into the water since it’s looking for its missing oxygen.

So which do you use on what kind of stains? There’s no real easy answer to this, since there can be a number of circumstances behind the stain. In general, an oxidizer (such as Pool Stain Treat) is usually the best bet to try first. Most stains will be removed by this, and these tend to be more cost effective.
If an oxidizer doesn’t work, a reducing agent certainly will (such as Super Stain Treat). This will attack the chemical bond and remove the stain from the surface. You may need to add a little extra to counter-act the oxidizing agent, but is usually not needed.
Keeping Stains From Coming Back.

How to maintain a stain free pool:

1. Balance
Most stain problems can be adverted by keeping your alkalinity in the right place (click here to read about the importance of alkalinity). In general, a lower alkalinity is better. Most pools will want to balance below 100ppm. If a pool has a stain problem, try lowering 10 ppm and see if the stains keep from coming back.
2. Stop Shocking
Shocking will cause stains. So stop it! In reality, using a good chlorine system, such as floaters, to keep chlorine in your pool rather than dumping large amounts in once in a while is more cost effective and safer (also, using No Mor Problems eliminates the need for shocking). If you need to shock, such as when using an algaecide that requires shocking, add the algaecide first; this ensures the chlorine will react with the algaecide and not the metals.
3. Think Preventative
Adding a preventative stain remover and metal removers will also help keeping stains off your pool. Most these will either be an oxidizer keep the stains in solution (such as Pool Stain Treat or Citrus Treat- for the all natural route) or will help filter out metals keeping their water content lower.All these help to keep metals from getting on the surface of your pool.
It’s also important to note that extra care should be given to Colored Plaster or Painted Surface
pools. Since most chemicals can cause uneven appearance of the color, you should always pre-dissolve a product in a bucket of water before adding it to the pool. This makes sure it forms an even solution in the water.

There you have it, the secrets behind stains and how to get rid of them. Now all you have to do is enjoy your stain free pool.

Welcome to the New United Chemical

Welcome to the New United Chemical Online

I want to welcome you all to a project years in the making. I’ve had a vision of what a website worthy to carry the name United Chemical should be. After all, we believe in providing the best solutions, and educating our customers in every facet of what we do. We wanted to build a site that was more than just a catalog of products, but rather useful, educational, rewarding. While creating products is indeed an important part of what we do – it’s not the only thing we do – and that means having a site that does more than talk about products, but also provides solutions that don’t come in a bottle.

This is that site.

I am proud to introduce you to the new United Chemical website. Here I’ll give you a quick overview of what makes this more than your typical product site, and show some of the helpful features you can find here, so let’s “dive in” (pun intended).

Learning Center Visit Learning Center

Pool Calculators

We have also taken care of the math of balancing a pool; with our Pool Calculators you can quickly calculate the balancing needs of your pool. Just type in a value, and our online calculator does the rest.

Q&A Forum 

Education is a discussion. That’s why we built an arena where you can get help from not just United Chemical, but other Pool Professionals and Homeowners. Odds are if have a question or a problem, someone else has had the same question – and can give you an answer based on their experience; it’s about creating a community of support – of learning – as we grow together.
