Low Phosphorus Flake Food

So I seem to always have a issue with cyanobacteria no matter what I do. All my fish are healthy it seems. I feed once a day rotating foods. I guess what i'm not sure of is if I'm feeding too much or if I have foods that are high in phosphorus.

What I am currently feeding
Omega 1 freshwater flakes
HikarI Sinking shrimp wafers
HikarI Algae wafers
Have fed API tropical flakes in the past

Are these good foods?

 

Giving this a bump up for you hope you get some responses today

 

The overall quality of those foods is fine, but I am uncertain ad to which foods has more or less phosphorus in them.

 

I think the ADA gold pellets have no phosphorus. Maybe give them a go.

 

Hahaha in my opinion a lack of phosfates can be the cause of cyano.
