Hi All
Im at the planning stage with my waterfall scrubber and im a bit confused as to why the recommended screen size has changed so much?
I was planning a large screen but after checking the latest thread i only need 3"x4"
Im planning to run it off my overflow but i think that it will be really noisey and restrict the flow.
Any help and advice would be great!
P.s im trying to cut my nitrate and phosphate levels in my tank as i have a bit of an algae problem
tank is 65G (UK)
Thanks
Matt
