Hi,
Here is a picture of my 30G (+/-) tank having problems with brwon algae tho' and am working to clarify the problem.
Attachment 2180
I have a sump/refuguim under the main tank with skimmer at the moment.
the light setup up is two coralife fixtures., one 2 65W flourescent, and one smaller coralife with 28W flourescents. Am looking to buy a 150W Halide Nano clamp fixture.
