Orb-3 PRA & Enzymes Maintenance N826

Why should I care about phosphate? Can't I just add chlorine or shock the pool to kill the algae?
Adding high amounts of chlorine or shock can often take care of the symptom of the problem - the algae - but it doesn't eliminate the source of the problem: nutrients.

The problem with relying solely on chlorine is that whenever the free chlorine (fc) drops and water conditions are otherwise right, algae will begin to grow.

By removing the phosphates from the water, you deprive algae of a critical nutrient thereby preventing it from getting established in the first place.

Chlorine is an important component of providing safe water for your enjoyment, however phosphate removal is key to preventing algae growth.

For a trouble-free pool... solve the root cause of the problem. Preventing algae growth is much easier than continually treating it.

I need to get rid of the algae in my pool. Can Orb-3 help me?
Yes! See our blog post: Identifying and Treating Algae in Pools.

How much phosphate should I have in my pool?
As little as possible... Most pool professionals consider anything over 500ppb to be problematic.

How do I figure out how many gallons of water my pool holds?
See our blog post: How do I figure out how much water is in my pool or pond?

Are there any animal products in Orb-3 Products?
The Orb-3 Pool & Spa product line contains no animal product whatsoever. All items are either food-grade or GRAS and are plant derived, mineral based or synthesized. They are non-toxic when used as directed, and do not contain phosphates, sulfates, or paraben; and are gluten free as well.

My pool water is cloudy, what should I do?
