Purple?

Wow, how can I build up some of that? That would look great!!!

a little brighter lighting should eventually do the trick.

Does the algae or diatoms eventually go away as the tank matures? Do you think it may be due to silicate levels? I used play sand btw.

 

[slipknottin]

silicate levels in the water possibly, not from the sand. (the silicate in the glass breaks down faster than the silicate from the sand...)

if your tap water has a decent amount of phosphates and silicates then yes, that is probably why your seeing the algae.

But with more light, the dominant algaes will be green.
