Black algae help

[gron47]

I have black algae and the pool is a little cloudy. I took a water sample in to the local pool store. They said I needed to lower my phosphates which is at 1000. They said since I live near farms that's why it's high. To reduce this and get rid of the algae they said I need 1. phosphate remover 2. 6 gal of chlorine 3. 1/4 gal of acid and rub a chlorine puck directly onto the algae.
Here's my numbers:
Cl =0, ph =7.6, alk =200, stab =100, hardness =1000+, phosphates =1000

All advice and help welcomed to remedy this issue and continued maintenance.
Thanks

I would do the test listed in this article to confirm if it was black algae: Pool School - Black Algae

If you are interested in learning about the methods we use here, know that they are contradictory with pool store methods. You can read more here: Pool School - What is TFPC?

We do not recommend phosphate removers as algae prevention. We use Chlorine to prevent algae.

Step 1 is to get a good test kit, Pool School - Test Kits Compared. I use the TF-100 from TFTestkits.net.
