Right now, you're nowhere near using TFP methods. Without using those methods, it's going to be extremely hard to help you.
You're dumping all kinds of completely unneeded things into your pool, and then wondering why it's not clean and clear. We can help you to get it sparkling to perfection, but in order for us to do that, you're going to have to stop throwing phosfree and algaecides and other unneeded garbage into your pool. TFP only works when you have a clear understanding of what actually needs to go into your pool to correctly address the issue you're having. Black algae can be addressed by simply adding enough bleach to reach SLAM level for your CYA reading, and holding it there until the pool is clear and passes an overnight chlorine loss test. That's it. No need to throw a bunch of expensive chemicals in there (especially not ones that contain copper), and no need to address your "phosphate problem" (there is no such thing).
If you're willing to head up to Pool School and read the ABCs of pool chemistry:
Pool School - ABCs of Pool Water Chemistry
Then how to defeat algae:
Pool School - Defeating Algae
And finally, get an approved testing kit and provide us with solid, self-tested numbers:
TFTestkits.net (I'd recommend a TF-100 - you're going to need the extra chemicals with your high CYA and your need to SLAM)
We'll help you get your pool looking freaking killer. But until you do that, it's impossible for us to help you because you're not willing to follow our advice.
This is a TFP pool - I've added nothing to it since I took it over from the former owner in April but liquid chlorine, some muriatic acid, and some stabilizer. I can see the head pattern on the drain screws which are 5ft under water:

Here's my "little" enjoying the water - you can see the sparkle and light reflection you get from extremely clear water:
Not a speck of algae, not a single day of cloudy water (pardon the little bit of scale on the tile back there, the house was a rental and the entire upper half of the tile was CAKED with calcium - it's been a long road getting it all off), the entire summer - with a pool that was running nearly 90 degrees temperature the entire time.
It's very easy to do - especially with a salt system (I'm doing this manually with liquid chlorine). But you have to stop padding the pool store's pockets, and choose to go the full TFP route.
