Hey guys just wondering if anyone uses a skimmer like fluvals? I'm finding alot of dust and surface crud on my tanks. It upsets me as my water is crystal clear.. Will that stuff make it tougher for the water to get oxygenated. I'm trying to minimize my surface agitation as i have diy co2. I know alot of people say there not and good on fw setups but i dunno what else to do. I just ditched the hob filter and never wanna go back
