Seven weeks seems a little early for Coralline algae IMO, but stranger things have happened. Does it come off the glass easily?

Doesn't look like corraline

I agree it seems too soon for that much corraline. If it wipes off easily it's probably green dust algae. Good luck

Its algae... normal.
posting nitrate/phosphate parameters may be beneficial..

but normal for new tank..

 

[gareth.hubbarde]

Nitrate 10ppm
Phosphate 0.5-1ppm

And there you go..

MORE water changes...

Yep water changes are abundant.
The algae on my back wall is turning red, is this normal? Also two previously white rocks are turning pink.
