The biggest difference between biguanides & halogens (chlorine & bromine) is the way the operate.  But first, let's look at their chemical natures.

Chlorine & bromine are both naturally occurring elements.  They have their own atomic weight & space in the periodic table (remember your high school chemistry).  Bromine & chlorine are combined with other elements to make up various chemicals & products that truth be told, we would have a very big problem living without. In residential swimming pools, chlorine tends to be in powder or tablet or stick form. Some people still use liquid.  Bromine is typically available as a tablet.

Biguanides on the other hand are not basic elements. Biguanides are "long string" polymers with really big names. We call them PHMBs (polyhexamethylbiguanides); even that's a shortened name!  Biguanides (in different formulas) are also used in veterinary (disinfecting) & human medicine (treating type 2 diabetes).  The real difference is how biguanides attack bacteria & algae versus chlorine or bromine.  Here's the difference:

Chlorine & bromine are like bombs or landmines that are in your pool water.  When the chlorine or bromine molecule hits a bacteria or algae cell, it basically blows it up!  It oxidizes the bacteria.  It's gone (as long as there are enough of them to combat the bacteria & algae).  Chlorine & bromine tend to have very low pH values making them "harsh" on skin & hair.

Biguanides on the other hand work like fly paper.  These long string polymers float through the pool water & attach to anything they come in contact with & eventually "strangle" the bad guys.  As that dirty string of polymer gets heavier with more dead stuff attached to it, it becomes large enough to settle on the filter & is filtered out of the water. Biguanides tend to aid making water clearer because they are a kind of water clarifier.  Biguanides are preferred by many people because they are much more gentle on skin & hair because their pH value is almost neutral.

With all of that in mind, let's show you how to...

SoftSwim Stain Control	treats heavy metals - iron, copper, manganese, calcium	1 qt. per 10,000 gallons	monthly	Prevents staining & interference of metals with Soft Swim System
SoftSwim Filter Cleaner	Biguanide specific filter cleaner - all media	follow label instructions	about every 6 weeks	Keeps filter cleaner by removing "spent"  residue
SoftSwim Assist®			Every two weeks	Prevents slime and mold from forming in pipes

One big problem is that Soft Swim or biguanide pools tend to be so easy to maintain that many, many people figure that they don't need to perform ANY maintenance.  The water looks great so if it ain't broke, don't fix it.  That attitude gets many of those same people into trouble with cloudy water and other problems that require time, effort & money to fix.  They then blame the product for their lack of care.  We see it constantly.  Don't fall into that trap.  Follow the doses & instructions & have a great experience!
