I've been using Reef Diapers for over a year. I love them. They literally kept me in the hobby. Cleaning filter socks was the worst experience ever. I would convert to a fleece roller but my stand is low and my sum has a weird lip. IMHO Reef Diapers are one of the best inventions this hobby has seen. The frequency at which I change them is based on the flow rate I'm running at that time. I was changing them 1.5 times per week when I was running lower flow rate for protozoa sterilization. I've recently increased my flow rate and now I change them every 2-3 days. I'm surprised at how much they pull out of the water.
I wish they made them with different pore sizes so I could go up a little and still pull out enough particles while changing one a week.
