Determining Fish load?

I have been searching and reading about balancing my tank. Its 6 weeks old, 65G, heavly planted and growing. I have 2wpg lighting, and 4x2l DIY CO2. I've been dosing with Flourish and Flourish trace 2x week per directions but have a batch of dry ferts on order from Rex. Link is sig has current fish residents.

My goal is low water changes and minimal dosing and getting rid of the algae! (just got over the brown and a week later I have Blue Green and a green wooly looking algae)

From my searches, its seems the best solution is a balance of fish load vs plant load, but there isn't really anything that discusses how to figure out where that balance is. I understand that there can't be a strict formula to find out how many fish are needed, but what are the things I should be looking for? Is there a rule of thumb per gallon or something like that?

I have been doing a weekly 50% WC since the tank is so new, but I never have any readable levels of amonia or nitrite (after the first 2 weeks). My nitrates however are also 0. Plants are growing fantastic and fish are really happy and active. Algae problems link says blue green is a lack of nitrates.

Should I limit WC to see if nitrate levels come up, or add fish, or somthing completly different? Whats a good process for acheiving the balalnce (for someone whose experience with planted tanks, is limited to 6 weeks).


More info:
50% WC yesterday morning with Flourish ferts after.
Tonight:
Ph - 7.0
kh - 11.2
= 33.6 ppm CO2

nitrates 0 ppm

Got my dry ferts from Rex tonight, so that will start as soon as I can get it organised.

Is 33ppm CO2 too high for only 2wpg lighting?

Thanks.
