    Others have asked and I would like to know who you got those from as well. I wonder if they will ship to the US as those look nice.

    Looks like there's a website ending in co.uk engraved on the top of the acrylic filter sock ... it's just at a really bad angle to make out ... anyone know what that site might be?

    Thanks,
    Harry

    Edit: Did a reverse image search on one of the pictures and found this ... seems to match the website address I mentioned: https://www.littleocean.co.uk/shop/crud-catcher-4-filter-sock-replacement.html

    Another thing I like about the cup is that it is quieter than a sock. The water flows into the cup unobstructed, while with the sock, the water hits the seam and is disrupted.

    i ordered the one from marine depot just because im tired of changing the socks. The one you posted looks good, but the diameter is 4.4 in so it would be a tad to big. Ill let you guys know if the ones from marine depot are any good

    I don't use filter socks but for those who do are they submerged in the water or above the water line? Most of the image searches show them submerged. My curiosity wants to know how that effects nitrates and phosphates.

    If you go to a pond shop they will have those black ones in different sizes, they are called "net cups" "netcups" .. And they come also transparent and white... search for them on Google and you will find them closer to your home than you expected.

    I ordered the marine depot ones as well. The cups themselves did not fit in my sump as the lip is way to small and just dropped through the hole cut for my filter socks. When I contacted MD they said this was a known issue and why they offer the cups with an additional ring attachment. I thought from the pics the ring was just for the C style sock holders but apparently you need them for some sumps as well. MD did me a solid and sent me one of the rings to try in my sump and see if those would work. I didn’t have a chance to try it out before leaving for a thanksgiving trip but will see if it works when I return.

    I have two of the cups on a reefer 450 - they fit well. I put a little fiber floss in the once a week for a day...

    I did get in contact with filterbag.com and the fellow I spoke to said they would have to get their plastic ring vendor to make a mold and minimum order for them would be 25,000. They have a company that only supplies them with the plastic rings and they attach your requested material. Red Sea knew what they were doing.
    I did get with BRS to ask if they would be able to have someone to have these made. No word yet.

    I bought the media cups for a 525xl sump and in about 2 minutes I can toss the dirty floss and replace it with new floss. Been using for 3 weeks and nitrates are still 0, but I also have an awesome skimmer.

    I use a pair of these Filter cups that you can get @ Marine Depot! They work ok, but nothing like a filter sock even know they are a pain in the a___ to change!

    I've got the red ones and love the fact that I don't have to clean filter socks.

    What do you put in your filter cups ? b/c if i use the blue filter pads my cups get clogged up in a matter of a day or two.

    Buy a big block of aquarium foam, cut into a round shape about a 1/4 wider than the cup diameter, and insert to the bottom. Make an extra set to have on standby. These rinse easily under the faucet and you can also place filter floss on top to extend the change out time.

    You’re welcome. My work here is done.
