I would just like to thank all you members who responded to my thread.

After acting like a nervous hen I put some of tips I recieved into play and my hair algae is retreating.

Even though it was an old method I used a phosphate pad in the sump.
I also ran carbon for 2 days and I am again running another batch of carbon for another two days.

Today I will be doing a 25% water change on the system. This should really help me out.

In the future I will be using phosoban as a preventitive and do a 5-10 gallon water change weekly. I have not decided this will have to be trial and error.

Again thanks to all you guys who added thier two cents. This is what I really like about the MAAST organization. Reefer addicts helping each other out.
