Question 1

Any one know what  the difference is between this product and Pool Perfect + Phos Free

Accepted Answer

Both are worthless! Look at the halosource sea klear phosphate remover, it actually removes phosphates from pool water! 32 oz. Of sea klear will remove more phosphates than 30 liters of phos-free.

Question 2

Do you still have to use shock if you use this product or is it used in place of shock? I am a brand new pool owner. Thanks for any help you can give!

Accepted Answer

These are very, very different products.  Phosfree is a maintenance product designed to keep pool phosphate levels very low-to-absent.  Phosphate prevents chlorine from killing algae.  If you have algae blooms already, you should shock and brush the pool.  Then test for phosphate (Natural Chemistry makes a very easy to use test strip; bottle of 10 for about $12, I think) and determine how much phosphate remover to use.  If you can, consult a pool supply store as to what specific product to use.  I like a concentrated product called PhosOut, harder to find than the Natural Chemistry series, but I think it works better for both treating a major phosphate level or for preventive maintenance.  Hopefully, you learn your lesson with the "major" level once and for all.  It's is very wise to be proactive at suppressing phosphate.

Question 3

Can you swim in the pool while the Phosree application and the pump ares still working to reduce the algae?

Accepted Answer

Yes...most definitely. We have been using Phos Free for several years and I also have the best looking pool. Works great and I put one capful a weekend in my inground 18x36 pool...

Question 4

Some algea prevention chemicals will add metals such as copper to the water.  Are there any metals in Phos Free?

Accepted Answer

This product contains lanthanum chloride.  This chemical binds with phosphates in water, making the phosphates unavailable as algae food.  It's probably not helpful to think of it as a metal.  You can find the material safety data sheet (MSDS) online if you want more information.

This product is not an enzyme.  The manufacturer does make other products containing enzymes; they usually have the word "Magic" in their name.
