Algea question

[matty]

Is brown algae a bad thing?

Depends on the algae species. Are you talking about brown macro algae or diatoms?

Diatoms unto themselves are not really bad as they are unsightly. Typically in newer tanks diatoms are part and parcel. As the tank ages some and the silicates in the sytem are exhausted, the diatom algae will crash on it's own. That is providing the water source used for top offs and changes is sufficiently pure such as RO water.
