Well, I'll chime in here as I am having the same problem ... GDA on the glass. My question is the same as ganjero's. What is out of balance?
Here's the info:
180 gallon (6' x 2' x2')
lighting: CF retro kits by A.H.Supply ... 2x96w & 2x55 ... I'm running ~200w from 9am to 9pm with ~300w burst from 11am to 2pm.
CO2: pressurized ... ~30ppm (or so the drop checker says).
ferts: macros on M, W, F, micros on T, Th, Sa ... I'm changing ~120 gallons/week via constant drip auto waterchange.

Less light than ganjero but LOTS of GDA. For the tank to be just "presentable" I need to scrub every other day. If I let it go 4 or more days, the fish become invisible
As you can see in the link, the tank is fairly well planted, and since that photo, the val has grown in significantly across the back.
I also am running a 55g and a 29g, each of them with 2x55w A.H.Supply Brite kits and I've no algae problems in either. A tiny bit of GSA in the 29 but a scrape when I do the weekly waterchange keeps that presentable.
So, is the consensus truly for a reduction in lighting period? I'm thinking the Blyxa will not be happy with that but it's certain that I'm not happy with the GDA and am willing to try just about anything.
Thanks in advance,
