Review on AquaClear Quick Filter Refill Cartridge for Powerhead Attachment (A578) - 2-Pack - Enhanced SEO by Amy Fenner

Featuring the Aqua Clear filter housing, this filter easily attaches to the powerhead without modification. If necessary, this filter can either be replaced or, best of all, rinsed under running water. I recommend flushing just enough to restore free flow through the media. Rinsing too often can remove all the good bacteria. Because this filter fits over a round frame, it becomes a hollow filter tube about 3/4 inch in diameter. Charcoal or other loose medium can be poured into it, making it a super filter. I am so glad I ordered this item.
