Getting brown algae in new setup...should I worry?

I just set up a 32g with 40w of light 10hours/day. I'm doing diy co2 (only for the past three days) and it's getting up to a measurable level now although it's not really in the good range yet. Anyway my question is, now I'm seeing a lot of brown algae forming on the glass and on my anubias. The co2 really made it take off. Should I clean it off? Will it die by itself? Do I need to increase or decrease certain ferts (doing ei)? I'm planning on getting some fish this week, hopefully I can get something that will eat algae but I've had really limited success in keeping anything that eats algae alive for more than two days. Poor stock I think. I'm going to try to drop acclimate since my pH in the tank is way higher than the store's pH will be and see how it goes.

 

Actually I have had the tank up for two weeks but I haven't really been doing any water changes, just fertilizing once a week since there are no fish. But maybe I need to do one and redose ferts before I add fish just to make sure levels are good. I can clean off the algae then and then see what happens.

 

After doing some additional research I think probably the brown algae is due to an overabundance of silicates in the water leaching from the sand. I hope this doesn't continue to happen since I don't really feel like unplanting the whole tank to remove the substrate. I know phosphate remover will take out silicates but it will also take out phosphate, obviously, which will probably harm my plants. But I could overcompensate by adding extra phosphate. I guess I'll give it a week or two and see what happens and pick up a pleco or something to start cycling the tank and eating the algae.
