Will using Phosfree raise my filter pressure?
Phosfree raises the filter pressure because it puts a coating on the filter media (sand, d.e., or cartridge) so it is able to catch the phosphates. After an 8-10 psi increase in the filter pressure, the filter should be cleaned or backwashed.
I've been told that my pool water is high in phosphates. I have used a phosphate remover to lower the levels but they were high again shortly thereafter. Am I doing something wrong?
There are several reasons why the phosphates can increase. Certain pool chemicals contain phosphates. Fertilizers and pollen can add phosphates into your pool too. You may need to drop down the phosphates as low as you can and use a phosphate remover on a weekly basis for maintenance.
(4 out of 5 stars) High concentration Phos Free

Pros: High strength Phos Free
Cons: Package does not include the Phosphate test tablets
My pool water had greater than 1000+ ppb of phosphates, giving dark blue color on the tests for phosphates. With such high level of phosphates, I was constantly battling with stubborn yellow algae. I had to get a couple of these 3L commercial strength Phosphate remover products.. and they have now considerably reduced the phosphates in my pool, and my algae issue is under control. I will keep monitoring phosphates ( I wish they had included the test tablets along with these bottles), and will consider ordering more of the same strength again.
(5 out of 5 stars) Best Swiiming Pool Product on the Market

Pros: It's simply the very best product ever!!
Cons: There are none!!
After using Phosfree in my pool to get rid of phosphates, I have eliminated the need for much else. I now add 4 oz. of Phosfree in the summer months every week. During the winter, I use 4 oz. every other week. You literally just measure it and pour it around the edges of the pool. I use chlorine tabs, baking soda (as needed) and muratic acid (as needed). It's simple, phosphates feed algae, chlorine kills algae and getting rid of the phosphates eliminates the food to feed the algae. I haven't needed any algae product in my pool since 2009. I don't brush the pool anymore, just let the Polaris do all that work. It's the best product on the market. One 3 liter bottle lasts all year. Inyo Pools not only has great prices, but nice, knowledgeable people working for them, and great delivery.
