🔍 Enhance Filtration Efficiency with MarineLand Rite-Size U Bonded Foam Sleeve for HOT Magnum Filter Review

They work great with the filter for my aquarium and as I don't live within 50 miles of a pet shop, I was glad to find her at Revain. They are well done. There were a couple of times I ran out without realizing it and had to rinse the used one to reuse it. Works great, no problems.

This is a set of 3 HOT foam sleeves as described. The price for three at Revain is less than one case sold in my LFS - must be inflated due to shipping costs to Hawaii. With Revain Prime or SuperSaver shipping, this is a great way to get cheap foam cases.

Yes, this is the right size. As in the HOT Magnum aquarium filter box. (This one lasted over 10 years so I didn't think I'd have to buy them in a 3 pack.) Needed as a pre-filter to prevent the Micron cartridge or media basket from clogging too quickly. Very durable. Washed and immediately back to work.

Originally they thought they were thicker and fluffier cases and felt terrible. THAT WAS NOT THE CASE! They last longer and filter BETTER than the fluffier version. (For the record, I use my filter in a turtle tank) I'm switching from fluffy sleeves to these.
