Review on Aquatic Experts 200 Micron Filter Socks - 4x8 Inch 🐠 - Short - Aquarium Felt Filter Bags - Custom Made in USA by Nicole Brown

Bought these for my 150 gallon saltwater tank. Arrived quickly, good price, well made. This is a mistake. They clog completely within 24 hours and severely restrict water flow and I only use a filter sock in a double flush refugium. My longer filters last 3 to 4 days before clogging. I also have an FX4 canister filter in my aquarium. to my sanctuary so that it has very clear water without algae. I wouldn't buy them for more than 75 liters. They're also more difficult to clean than longer ones because they're so small they're harder to turn inside out to clean. Lesson learned.
