Review on Filter Socks 200 Micron Aquarium by Lisa Weigel

Bought these for my 150 gallon salt water tank. Arrived quickly, good price, well made. completely within 24 hours which severely impedes water flow and I only use one filter sock in a dual flush refugium setup. My longer filters last 3-4 days before clogging. In addition to my refuge, my pool also has an FX4 external filter so that the water is extremely clear without algae. I wouldn't buy them for more than 75 liters. They are also more difficult to clean than longer ones as their small size makes them harder to clean. Lesson learned.
