Cloudy Water in Biguanide treated swimming pools.

Let's first say that as with any pool chemical maintenance program, it is always preferable to prevent rather than treat problems that can occur.  This includes proper water balance - pH 7.4 - 7.6, total alkalinity 125 - 150 ppm, calcium hardness about 200 ppm - and chemical maintenance - regular, correct additions of BioGuard® Soft Swim® A, B or C.   Along with regular filter cleaning, pool maintenance (vacuuming, brushing & cleaning) and regular additions of BioGuard® Optimizer Plus® & BioGuard® Soft Swim® Assist, you can have a great non-chlorine, non-bromine experience year after year after year.

One of the "problems" with biguanide systems is that the pool becomes so easy to maintain, many pool owners miss or omit their maintenance routine.  This is "done" by neglecting to shock (number one omission), vacuum, brush the walls & clean the filter.  The thinking is, "the pool looks great, I don't have to anything this week.  I'll let it go."  You're looking for trouble.

Cloudy water - normally (almost all of the time) seen or experienced because the pool has not been properly maintained. Period.  The typical scenario that we see is after 4 weeks, the water still looks great.  Pool owner won't shock it because "it doesn't need to be shocked."  The water is still nice & clear.  The pool should have been shocked more than a week earlier.  The pool owner was "saving" money.  Algae & bacteria begin to grow aggressively. The water has a slight haze to it.
