3 socks from Blue Life to help maintain the clearest of water.
200 micron filter sock - great for general everyday use, reusable and made from polypropylene so you know they'll last a long time even when bleached regularly
10 micron filter sock - works perfectly with the Blue Life Phosphate RX to immediately drop phosphates. Use in emergencies only, but these socks help to bind phosphates and allow them to be trapped in the sock and then simply removed after treatment
200 micron mesh filter sock -for an even easier clean, simply remove, hose off and reuse
