Just curious who has stopped using their sump filter socks. I've talked to a couple of people here on Wamas that have decided to stop using them and had good results. Depending on how frequently you switch them out, I would assume there would be a nutrient increase. I've used them for a long time, but like to evolve with the times. I don't like the fact that the socks filter out coral food, but I want to hear some "case studies" of people who had good luck.
The other thought it to just go to mesh socks. This would help with micro bubbles, but let the small stuff through.
I'd be interested to hear what you have tried and how it worked.
