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

I love them, but didnt read to rinse before using. Maybe a red warning tag right on the filter sock would help us who dont routinely read the paper instructions. It did foam everywhere, and clogged up the air intake to the protein skimmer. Maybe the company should actually rinse them before selling the product. We all have expensive fish, and I am wondering what was in that massive amount of foam. Thank goodness the fish all seemed unaffected by the foam produced.

I pay $13 a piece for these at the fish store. Really good buy and they are exactly the same.

not bad, not great. just an average filter sock, price is good.

great socks ,they catch a ton of particulates

Just what I was looking for. These are very large socks work great. I recommend them Thanks

I like these filter sox for my 125 gallon saltwater tank. I shall be back for more!

PRO - Does a very good job of filtering unwanted waste from aquariums and traps it in the socks, easy to replace. CONS - Needs to be replaced often to maintain high quality filtering, would be nice if they didnt clog up so fast.

The opening for this filter sock is - I guess as they indicate 7 in across- was able to squeeze into sump and doing a good job without question- opening with plastic ring will flex to a degree and thus able to maneuver in- content with job its doing

Been using these socks now for over six months and they seem to do a great job of capturing debris from my 365 gallon salt water reef tank. I’m very curious to see how long they will be usable but right now very happy!

Great value
