Fette Filter - 10 Pack Polishing Internal Canister Filter Compatible with MarineLand Magnum Polishing Internal Filter JH Cartridge

Tighter looking weave when you hold them up to the light. Fit the internal core perfectly. Inexpensive enough that I can change them out frequently. I will purchase again, I've been converted! Ordering my second box (10/2020). Really polish my water. Using these in a salt water quarantine tank that I hold livestock in for a couple of months before moving to the display tank. The Marineland internal filter is a good value; using these filters makes it a great value.

Can confirm these fit the now no longer sold on Amazon “Marineland ML90769 JH Floss Sleeve Magnum Polishing Internal Filter (3 Pack)”. They are cheaper quality, but they are priced lower too. I don’t know why the sizes are listed differently, but they do fit.

Works great in the new filter system for my fish.

Does the job it was designed to do and fits like a glove

I'm really becoming disappointed with Amazon. Lately everything I get is wrong or cheap junk. Don't waste your money, these do not fit Marine Life Magnun as they state. They make returns difficult, it's now more costly to return than just keeping it. Do not buy!

A much less expensive alternative to the brand name and works just as well.

Absolutely grabs all the small particles in the water my turtle tank is clean and clear

Works just as good as the name brand filter covers.
