Hello!
I write from Italy, I have a 1100-liter aquarium, and I recently adopted the filter algae. I have no problems with filamentous algae in the main tank, but being a habitat with non zooxanthellae, I need to feed constantly, and I adopted the philosophy of the aquarium without a skimmer ... I set up the filter with 4 105W CFL lamps (40 cm long and weighing about 2 kg each) 2700 ° 6400 ° k and k. .. I hope you like my set-up.
ps: sorry for my bad english
