Want To Grow Algae In M Mumba Tank

[cuprajake]

hey guy's

i havent been on here much as i moved from my ei planted tank to malawi

im now wanting to grow lovely green algae on my stone work,

i still have my ei dosing stuff left over

i have:

Potassium Nitrate
Potassium Phosphate (monobasic)
Traces

im thinking i need to feed and grow the algae so i wondering how many ppm of the traces i would need in the tank?

i have upped the lighting by adding some of my old planted tubes so im currently running:

36" flora growlux 30wt
36" fresh water lamp 30wt
30" marine white 30 wt

so that gives me 1.8wpg now, the two 36" are going on from 10am to 10pm, then the marine comes on at 4pm till 10.30 ish this hopefully will give me plenty of light

heres the tank
