These bags are perfect for not only holding purigen but also for regeneration of purigen. It holds up to the heavy bleach solution required to regenerate purigen without breaking down like similar competing bags.

Perfect!!! I use these to capture the debris from my large pre-filter on the intake of my Fluval 207 when I do a water change or give the pre-filter a rinse! Works perfectly! Well made filter socks. Love this company!!

Great filter. I cut to size and use on my home aquariums. It does a good job of capturing all the fish waste. Very durable as you can rinse the filter several times before having to replace it.

The 50 micron polishing pad works great. I cut it to fit my HOB & let it do it's job. My tank is always crystal clear. I'm very proud to show my guests when we have a get together. Thank You for a great product.
