*NOTE: Please rinse all filter socks prior to first use

Filter socks are the most convenient form of mechanical filtration. They remove excess food, detritus, organic waste, dust, and other particulates. Removing these particulates from the water column will reduce the amount of organic matter that produces ammonia and other undesirable substances in the aquarium. Filter socks also help prevent larger objects, such as sand, crabs, snails, etc. from damaging pump motors. Regular filter sock use will lower organic levels and result in CRYSTAL CLEAR WATER!

No holes in them socks

the filter socks work great, I change mine out every three days so I keep about 20 of them on hand. I wash them in the washing machine 10 at a time with small amount of bleach,then rinse the out and hang out to dry.

Works too well

This is my first experience using a sump with a filter sock. The sock itself catches so much material that I have to clean it out every day. Every evening the sock begins to overflow. Once I clean it, it works fine.In addition to two engineer gobies and a dwarf Angel, I have three large damsels in a 75 gallon reef tank that all tend to constantly stir up the sand and produce a lot of waste. I'm sure this contributes to the filter sock clogging rapidly.Overall, the filter sock does it's job extremely well. But, it may be doing too well for my tank set up.

Excellent product

I recently order the filter sock and I very impressed on how crystal clear the water is. I ordered three to substitute them when they get dirty. I switched to a new one after a few days. Note, I recently upgraded to a 90 gallon tank from a 40 gallon. I had extra live sand laying around so I placed that in the new set up algo with live rock from my old tank. That created a lot of dirty water but the sock took care if that after a few hours. Great product.

Berlin Filter Socks

Okay. I ordered the filter socks. And what a dummie. I ordered 7" and didn't look at what that meant. Open the box today and I got 7" around thought it was 7" long. Called no hassle, receive and RMA. This is a great company. I'm a customer for life.

Great filter sock

Good build quality. The seems are tight. This thing does a great job of trapping everything that comes down the overflow. This sock is pretty big, so keep that in mind if you have a smaller sump.

Great filter sock

These filter socks are awesome, they catch so much junk out od the water. I wash them inside out in the washing machine with bleach and two old towels that I use strictly for tank stuff. After I was the socks I rinse them in ro/di water and a drop of dechlorinator. These things are awesome!
