Out of curiosity, how long did you leave the lights on for which resulted in the algae outbreak? I'm hoping I can battle the algae by limiting the turn-on time for the light, and adding the 2 BN plecos. Since I'm steering into the direction of low light plants, I'm hoping that won't limit growth.
I left the lights on starting for 10 hours before realizing how much light it was. Dropped it down to 8 hours and started to get the algae under control before making the switch to the other fixture. I was in the same position where I couldn't hang the lights because of where the tank is. Next best option would be the raisers like theericafish mentioned. I remember seeing them at one point but can't remember who it was selling them.
I would stick to a single bushynose unless you are really into plecos. They just have a relatively high bioload and don't consume all that much algae. I always keep one because I like them. Consider some otocinclus and japonica shrimp.
As the tank fills in more and the filter starts to break in you will notice the flow is reduced. Are you sticking with strictly plants or have you considered some hard scape?
I can't tell for sure form you photo but that plant in the back looks like dwarf cardinal. Like I said, just a guess though.
