I have 18 Gallon tank and I was having below fish
  • 3 fancy Guppies
  • 6 Cardinal Tetra
  • 1 neon blue Gourami
  • 2 Amano
  • 4 Ghost shrimp.

I have below plants
  • hair grass
  • Aanacharis
  • Java moss on dog wood
  • Anubias nana
  • Cabomba Caroliniana

I have issue that my water is today slightly green with green and brown spot on the glass. It is only start.

So I will make black out for day or 2 but on second thought, I feel my hair grass will get effect. Some people are telling use Seachem Excel but I am afraid to add that.

Clean first. Scrub the glass wherever you see the algae, clean around the edges and vacuum the substrate good. Then do a normal 30% water change or so. That may be all you need to do, really. Doesn't sound too bad yet, may just be extra algae and not a bloom, but clean, and do your two day blackout if you want to. =)

not really advice on what to do, ...

brown 'water?' on sides
water is slightly green

brown on sides - diatoms or green dust algae - if so doing nothing (not wiping down glass) will clear up on it's own (regardless of algae)

greenwater, ... that's never fun :(
