Algae, Algae, Algae!

Greetings,

Just looking for some advice on algae control. I made the mistake of filling my tank with tap water (have a ro/di now). Couple of questions pertaining to different types of algae (mostly curious what you guys do):

1.) Brown Algae on glass - Asides from scrapping it, what is the best method? I have a bunch of snails, and they don't need seem to be keeping up.

2.) Bubble Algae - no idea what to do about this guy...

3.) Algae in sand bed - I really want a white sand bed. I think it makes the tank look amazing.

One other point. I am having amazing coraline growth right now on my new rock. The colours are amazing. Green, orange, white, and purple. I don't want to do anything to jeopardize this growth.

Details about tank:
55g
Weekly 15% water change
Prizm Skimmer
Two 802's and a 402 for circulation
Coralife Lunarlight - 48" 4 PC - 260 watts
(will be a remora pro in 2 weeks when I get my 33g sump going)
10g refuge will be set up in 2 weeks as well

Thanks a lot!
