Blue Lights

[paulc]

Hi All

I came across a post on another forum that mentioned that blue lights can cause algae in a planted tank? Anyone have any views on this?

No they don't...Ammonia and too much light cause algae, not the colours of the light. This is an old school way of thinking.

Thought as much - cheers Ian - must stop reading lol

it's good to read, just don't take everything as gospel that you read on the net without looking at reputable sources.

Colours of bulbs are measured by kelvin ratings.

heres a good thread to read through.

the discussion starts about half the way down. I do have some research articles on it it you really feel the need.
