Resistant green hair algae

[SaltyDog706]

I mentioned this in another post a week or so ago.
I had a fair amount of green hair algae and a lot of dragons breath algae in my tank and when I mentioned this to a friend he suggested I try a particular mix of phyto that he was producing / selling. I did. Two weeks later all the algae was gone..3 months on..it hasn't returned. I still dose about 50ml of the phyto every two days in a 240lt softy tank. Also..my phosphate is now stable at around 0.03 - 0.1.

What was the type of phyto? Thanks in advance!
