Question Which Dry Ferts with Flourish ?

I have a 36 Gallon tank (20-21" Height) that has been set up since Nov 2011.
Current USA Nova Extreme 30" 2x24W T-5 10,000K - Freshwater Light (7 hours a day, sitting on glass).

I currently dose 3ml of Flourish and 3ml of Flourish Excel 5 days a week.
1x 50-60% water change a week. Flourish Tabs every 3-4 months.

-The Argentine Swords, Wisterias and Java Moss has been growing great.
-The Italian Vals, Anacharis started off fine, with it spreading throughout the tank, but some are slowly browning and falling off.
-The Onion Plant, Banana Plant hasn't changed much.

There are some black-ish algae growing (looks like black hair algae).

From what I understand, Flourish only contains trace elements, and plants still need macros. So I wanted to start dosing with dry fertilizer.

How does this look?

Sunday - 50% Water Change
Monday - 1/4 Tsp-KN03
- 1/16 Tsp-KH2P04
Tuesday - 3 ml Flourish
- 3.6 ml Excel
Wednesday - 1/4 Tsp-KN03
- 1/16 Tsp-KH2P04
Thursday - 3 ml Flourish
- 3.6 ml Excel
Friday - 1/4 Tsp-KN03
- 1/16 Tsp-KH2P04
Saturday - 3 ml Flourish
- 3.6 ml Excel

Any other suggestions?

You very likely have high light now. And, you don't seem to have CO2. That alone means you will be very likely to get BBA established, and have a long battle getting rid of it.

In my opinion, your first move should be to raise the light to about 6 inches minimum above the top of the tank. Then, you can follow that dosing schedule and have a chance of avoiding a major outbreak of BBA, as well as other algae.

Or, you could put a layer of Home Depot fiberglass window screen (insect screen) between the light and the tank. That will drop the intensity down into the medium range. Two layers will drop it down to low light.
