4 Pack - 4 Inch Ring Filter Socks 200 Micron - Aquarium Felt Filter Bags -4 Inch Ring By 9.5 Inch Long [Short Version] - Fits Eshopps and Aqueon

Love these socks, I have purchased multiple times. I have washed mine 4-5 times already and they keep going. I clean with a high setting on my hose, store in a bucket until wash day, soak in bleach, wash in bleach, add extra rinse cycle. Dry for a couple days in the air, then use seachem prime usually before putting in the tank. Great quality, perfect size, very easy to clean, and functions like it should. I am not sure why other people have had issues, I have never had issues and will continue to buy more as needed.

Got these to replace a few of the ones that have since torn off the plastic hang necks after a few years of use (OEM). Shorter length as is designated in the description than the previous ones I bought but made much better. The filter sock is actually close to double the thickness and around the plastic ring neck the fabric is actually sewn on (and sealed) not just heated or glued on like the originals were. I had purchased a few extra sets of 3 when I bought the eShopps rs175 for my 36 gallon bowfront Saltwater/Reef tank as backups and noticed that after a few years the ones that weren't used seemed to get somewhat brittle around the neck and tore very easily rendering them useless after only a few times of use. I think because of the thickness of these they make take a little more time to clean but that's fine so long as they work and last. I changed my filter socks every 3-5 days and then soak them in bleach water for a week or so. Rinse and clean them in the shower to remove the chlorine bleach and then soak them for another week or two in RO/DI water. Has worked great for over 6 years to clean filter socks. These are absolutely an upgrade in quality from the originals!

Worked well! Good value for the money. Fit perfectly, easy to clean though there was a little "shedding".

Great filter sock mine were getting used up so I had to purchase more never bought these but they feel the same as any other, except that they are shorter.thats why I’m giving it four stars. Not the full length I was expecting other than that I’m satisfied at the moment time will tell how good they hold up after washes etc.

Nice filter sock. Soft . Easy to clean. Would purchase again

Good product

Works well and fits my IM

I only use socks when the water needs a good polishing or during bi monthly maintenance. These socks have been cycled a dozen times each and hand washed afterward, which in my case means being forced inside out. Other low cost felt socks have split at the seam or broke the adhesion at the ring after just 3 or 4 washes. If I ran socks continuously, I'd buy 4 more sets of these.
