Seems honeymoon's over and I got algae. well 2 sorts of it.

1st (it's not on the glass though it might look like it is):

This one is on the substrate. looks very similar in color to the small spirulina pellets I tried to feed on the discus. Its dark green in color. I could be mistaken that it's the pellets though.

Possibly brown algae according to this site => http://www.theplantedtank.co.uk/algae.htm

It is light/dark brown. seems to be spreading on the substrate and there are patches on the glass.

The link (theplantedtank.co.uk) I mentioned has suggested a treatment of sorts for the brown algae if my guess is right. Should I just follow it? Any ideas for the "dark green" algae?

Thank you very much :)
 
Not very long. Probably around 4-5weeks
 
Ok, that makes sense. The brown algae will be diatoms - very common in new setups. Leave it be or wipe it off the glass, but it should go after a few weeks once the filter has matured.

The green algae could by Blue-Green-Algae or Cyanobacteria. Check how much flow you have over the affected areas.

That side of the tank gets pretty good flow Much better than the other side. Would you recommend a total blackout like what is suggested in theplantedtank.co.uk? My only concern is the discus. Thanks again.
 
Hello,
If the tank in question is that described in your signature then it is recommended that you avoid using 450 megawatts of light and reduce it to something more reasonable, otherwise it's highly unlikely that you will resolve these issues easily.

Cheers,
