Phosphate questions

I'm having some minor issues with hair algae. Had my water tested at my LFS as i don't have the test kit for phosphates yet.

i have some phosguard that i have had for a while and thinking about adding it to my filter basket.
any advice ?

29 gallon
rotala, crypts, HC, ludwigia and anubias

Anywhere from about .5 on up is fine. I have seen some test results of about 4 or 5 ppm. Phosphate is not the cause of algae. Phosphate is a plant fertilizer.

Tell us more about your set up?
Lights, CO2, substrate, fertilizer schedule, stocking...

29g
temp 75ish
7.4 ph
gh 22 high
kh 16 high
nitrate 12.5 ppm or less (tetra kit only shows 12.5ppm increments)
T5 HO 10k/colormax 9hrs a day
pressurized CO2 3-4 bps
Flourite with inert top layer
hob 350
powerhead for circulation

Flourish 1/2 cap weekly after weekly %40-%50 water change
started dosing 1.5 dose excel to fight the hair
I scaled by photo period back to 9hrs from 12

12 Rasboras
4 serpae
4 oto's
1 Dwarf Gouramis

I shortened the photo period and started excel and that has helped a great deal but I have not quite gotten it out yet. I still see some in the roots of my HC. I actually believe I had some get smuggled in from a new bunch of Rotala. and about that time I also got fed up with a red tail black shark and plopped him in the African tank. That's about when I started to get over run. Then i added the otos.
