Testing Your Pool For Phosphates 

I’ve been servicing my own pool for approximately 18 years and had no clue about phosphates and how it relates to algae. This information is so helpful and much appreciated.

I use a special test strip in a tube and you have to look down in the tube with a white paper underneath. If you have phosphates it will colour blue and you can measure it. I have a limit of 500 ppb (yes, billion). If it is higher I use a product similar to Orenda. The first time I used it my pool had 1000 ppb and the product turned my crystal clear water milky white. It scared the shit out of me! But after using a clarifier it went crystal clear again...thank God. Then, I got from 1000 ppb to only 100 ppb. I now have 200 ppb and discoverd my tap water has 80 to 100 ppb. Water evaporates....voila phosphates will increase in due time. If you cut a lot of grass near the pool this will also increase phosphates. Thanks for the video!

Amazing! Now I can return the expensive test kit I bought!

thanks for the video Kenny. Pool professional here and for the past 2 years, ive used Orenda pr10000 and have never used algaecides again after your recommendation. Yellow algae is especially tough and orenda takes care of that. one thing i noticed is that instead of using a full 8-16 oz, treating it with 2 oz per week worked best for me because the filter pressure doesnt increase. For cartridge filters, i saw that this product had barely any effect on filter pressure.

Great information, Sir. I just put 48 oz of NoPhos into my 35k gallon pool. It will need another 48 oz treatment to get rid of all the phosphates. At least now I know how to test for it without making a 40-minute drive to Leslie's. Thank you for sharing.

Thank you for your video!

Thank you, your channel is by far the best! Question, do I backwash DE filter after treatment

That is awsome phosphate remover !!

It's best to start with a clean and charged DE filter and then clean and recharge again after.

Great demo, Kenny. As an aquarist I'm aware of concern about phosphates. For those of us with DE filters, is this something that will clog the filter? If so, I'd wait until it was nearly time to recharge the DE anyway. Someone before me decided a couple silver maples around the pool would be nice, and they're beautiful shade tress. But boy howdy do they shed all manner of twigs, seed "helicopters" and then finally leaves that go into the pool. Phosphates are real.

Thanks for the vid. It really helps. Looks like your in val vista lakes. im in san tan. Leslies said i have 3164 phosphates in the pool shouldn't be higher than 100. lol Have you noticed an extreme amount of calcium in the pool and pipe outside the house? How do i get rid of it? Its on the pebble tech and the rock water fall.

so assuming all that cloudiness ends up in the filter, do I need to backwash the filter afterwards ( using DE-type filter). I have heard others say I should turn filter off, wait until precipitate gos to floor and then be vacuuming to waste, but since I don't have a pool vacuum per se ( just a robotic cleaner), I think this system seems easier.

So do you recommend doing a backwash and rinse on a sand filter a few hours after doing this or perhaps the following day?

What would happen to pool or swimmers if not treated with phosphate remover? Can you do a video on organic yellow stain on concrete ungrounded pool? I heard vitamin c works but need the process detailed.

If a pool has a cleaner, do I need to shut off the side port so the cleaner won’t run?

Also if i use the pr 10000 how many hrs before i can get in the pool? just until it clears?

So do you only apply this product after a filer has been cleaned or can I do it at any time?

Once i kill algae do i need to vacuum to waste or will it disappear by itself

Hello Ken, can use this in a salt water pool?

What speed should I run the pump? I am running the pump for 48 hours.
