I recently watched a video on YouTube about a filter cup that’s basically a filter sock, but overtime is cheaper and just as efficient. This seems like a very good solution to the filter sock, but I can’t find much information on it. There hasn’t been any posts on it on YouTube in a year and the website says sold out. If anyone is familiar with it do you have any updates? If not, does anyone know something like it? Here’s the link to the product, https://reefingainteasy.com/
