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

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

Exactly what I needed! Good value.

This is the first time weve used these filters and if they were not going to work we were going to give the fish away and be done with the aquarium however the filters work like magic!

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

Good Item

As advertised

Work great. Keep water clean and clear. Good deal on how many there are in pack.

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

Easy to replace, works for 2 weeks then needs replacement. Works well

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