Green dust algae infests my high light 29G. In this same tank, there are no other noticeable algae present. The algae appears to be light loving; but short of reducing lighting levels and/or through an UV sterilizer, what else can I do to curb its growth on the glass walls?

Plant growth is excellent: no deficiency and/or toxicity that I am aware of. Pearling occurs ~4 hours after the lights are on. I don't test for any parameters, but the following is my weekly fertilization regiment.
Pressurized CO2 at 1.5 bps, with external reactor powered by Rena Filstar XP3 canister filter.
CALCIUM/MAGNESIUM
3-6 dGH from CaCO3 & MgSO4.7H2O (0 dGH from tap water)
NITROGEN
32.57 ppm NO3/week via KNO3
PHOSPHORUS
1.86 ppm PO4/week via KH2PO4
MICRONUTRIENTS
1/64 tsp Plantex CSM+B 2x/week
1/64 tsp Sequestrene 330 (10% FeDTPA) 1x/week
Moderate fish load with feedings every other day of live grindal worms, flakes, or frozen bloodworms...depending on my mood for the day. :mrgreen:
That comes out to be ~4.65 ppm NO3 per day. That's the minimum amount required (in this tank) to keep the leaves of Micranthemum umbrosum large and robust. Aside from being a phenomenally attractive plant, it is quite useful in the determination of the nitrogen needs in my tank.
Please advise. Thank you.
