Nuvo 8 Gallon Nano Reef Tank

[chromakey]

Good Day:

I have a 8 Gallon Nuvo reef tank setup. I have two small clowns that I would like to keep in the tank. The light is stock and it keeps the macro algae and mushrooms growing. I use GFO/Carbon in the back. I do water changes every two weeks. All parameter are good for the tank but has anyone added extra filtration?

Thanks,
Michael
