  • Good filters
These socks fit my fijicube kit sump, they filter better, for longer than the fijicube socks that came with my sump kit.

  • Great product - Wash First
Make sure you run these through the washing machine. Lots of starch on these and they will make lots of micro bubbles that will make your skimmer go bonkers. Besides that its a quality product.

  • OK Filter Sock
These are OK. A little stiff - which makes me wonder what they're made of. But, generally they work. I was annoyed to have to remove a tag from each one though.

  • Love the size of these.
They are slightly shorter than the ones I was using previously. This makes them very easy to change in my sump.

  • false description by seller, not made for red sea.
3rd time ive used key word red sea 4" filters but are too big and do not fit into genuine red sea brackets. I'd ask for a refund but I had to butcher up 1st set as well as my original brackets after removing dirty filters...... now I only have to butcher 7 more sets to make these usable.

  • Great value filters
These fit my tank perfectly! They're definitely thinner than other filters I've used, but they seem to catch the same sized debris as far as I can tell. What that means is these will clog sooner than the thicker filters, but these cost substantially less so I don't mind having to change them more often! My only concern is that they might not last as long overall, but again, the price of these makes that something I'm willing to compromise on. ... show more

  • Stain easily but do a good job
Even after bleaching, I can't get the stains out. Other socks I have no problem with this. However, for the money, they are a good value and I will probably buy more.
