Aquatic Experts 7-Inch Ring 200-Micron Felt Filter Socks (7 x 12, 2 Pack)

The filter socks are great. They fit perfectly. One word of caution when washing them. I followed your instructions and used the heavy duty cycle and it all but destroyed the socks. Since that experience I have used the gentle cycle and it works much better.

Thank you for the tip on rinsing the filter socks prior to using them. I was not aware of that and my protein skimmer did go crazy for a few days and bubble over. I can see now why the importance of rinsing the socks well before use. I have successfully raised fresh water fish for 20 years and now am making the transition to marine. Wished I had done this many years before. Am looking forward to getting my first 300g tank set up and running. Thank you,

These filter socks leave my water sparkling clean.

Just washed these for first time. Regular cycle, cold water, lowest speed spin. Washed six together but in separate load. Air dry. They came out covered in fiber pills many of which were loose and readily brushed off. I’m worried about the micro fibers they are going to shed in the tank if I try to reuse them.

I love these socks! They fit so much better in my Tideline sump by Trigger Systems! The origional one that came with the sump is too long in my opinion and the 12 by Aquatic Experts is the perfict fit for the Trigger Sumps!! I will be ordering more soon!!!

As advertised.

Best by far. Using them on my 20 gallon freshwater sump

Garbage. For one theyre way too short. You can pay the same price or less and get a full-length filter sock. Secondly, and more annoyingly, they do not fit snug in a 7in filter circle. I had to basically weigh them down with rocks otherwise the water would have gone through. Of all the filters Ive purchased on Amazon these are the worst.

Really good filters. Just make sure you wash them first on gentle with an extra rinse

good so far
