Really?? I think this is the cause of 90% of the algae. People thinking that they need something like 4 wpg for high light. With 2WPG T5 and good reflectors I can grow any plant I want, ANY! Not one failed due to too little light. When I apply 1.5 wpg above my tank, even suspended a few inches I get a PAR of 200 at the substrate, and in the corners about 75. How is this low light? I think this is only low light if you use T12, no reflectors, bulbs with terrible PAR or a tank below 5G. To tell you a secret, there is almost no one who uses more than 2 wpg in the NBAT (Dutch contest, try googling it).
The big problem with the assumption that you have low light, is that you won't need high CO2, not much fertilizer etc. I can grow glosso with only 1 wpg (it grows up a little, but this stops at 1.5 wpg). What I'm trying to say is that WPG tells you nothing, and that people always advise too much light. I know, I started with over 3 WPG as well, uncontrollable and unnecessary! CO2 is much more important in those so called high light plants, especially when using EI! So to reply on the OP, I think you've a good start, try to make sure CO2 is enough (1 bps tells me nothing) and focus on maintaining your tank pristine!
