A few days ago I had a subscriber wanting to know more information about phosphates…what the are and how to best treat this dilemma.
It’s a much needed topic to address…
What are phosphates: Simply put, phosphates are made up of plant nutrients. The problem is that they can enter the pool from countless different sources. Here’s the “short list”…bird droppings, leaves entering the pool from winds, clothes, dirt, rain…even tap water! Just about everything that can enter your pool either has phosphates or has the potential of transferring them to your swimming pool.
Many people think that just because they have chlorine in their water (either via traditional methods or through a salt system) that they’re pool is immune or the chlorine kills off any phosphates. Unfortunately, phosphates are immune to chlorine (unless you literally NUKE it with chlorine).
So, why the big deal anyway?
Good question…phosphates are THE food source of algae.
All types of algae found in pools THRIVE on phosphates – this is what “they” eat.
When you have algae in your pool always have the water tested for phosphates – especially after a heavy rain or winds.
Phosphates should not exceed .1 PPM.
If it does, here’s a couple of treatment options.
1. Phos-Free
2. Phos-Out
3. Phos-Guard
Phosphates are something that every pool owner will deal with at one point or another and it’s nothing to take lightly. Using a solid phosphate treatment is a great regiment to incorporate during the swim season. I like to use at about once every 4-6 weeks during the swim season – you may choose to use more if you live near farms, in an area of heavy winds or you get quite a bit of rain.
How To Arm Yourself And Get An
“Unfair” Advantage…
I spend quite a bit of time inside The Chemistry Wizard dealing with this topic and practically every other chemistry related issue on the planet. Ultimately, when you understand what’s taking place in your water…and why it’s taking place you’re able to arm yourself with the appropriate information to be PROACTIVE instead of reactive.
Those who are proactive ultimately save money on their pool.
All the best,

Will phosphate treatments interfere with other chemicals that are used in the spa? I hate when the water gets a chemical smell.
Instead of having to replace my vinyl liner,how can I repair a hole in the corner?
In ground pool liner 22/40 ft. The hole is larger than a patch.
