Marina (3 of Each) Slim Filter Carbon Plus Ceramic Cartridges and Zeolite Plus Ceramic Cartridges

These go with the 3rd filter system I tried... FINALLY found something that works.. water so clean now... low maintenance!

Work well with intended filter. Look for the deals on these- many are overpriced listings.

Filters dont last long

Got this because it was supposed to be 3 of each type but was just 1 type and 6 of them

It’s a great deal

These are perfect for my small fish tank at work that I have about six Fish keeps it clean for approximately six weeks

WISH THEY PACKAGED MORE FILTERS OR THE PRICE WAS LOWER. GREAT IDEA IF WE COULD CLEAN AND REUSE THEM. RON P.

This is the product we absolutely need for our aquarium and the price is good on Amazon. Having it delivered is one of the bonuses because we have to travel quite a distance to the first store that carries them.

Refills for the slim 20 filter, new set up and the 4 filters seem very efficient, fast water clearing and now maintaining a good water quality. Very satisfied. Nice to get an very quick and early delivery. Thanks.

My local fish store was selling one pack of 3 for $12 and I paid two packs of 3 for $6 so I think I won (sad i didn’t support a local business tho)
