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

This is a great product. I should have purchased this before any other products

Ive used this brand for over a year and like the convience of ordering at Amazon.....and the protect is mess free.

Exactly what I needed! Good value.

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

Kept my tank clean for 2 months without changing the filters

This was exactly what I needed!

As the picture shows, I received 3 packages of the Bio-Carb cartridges with the Zeolite nowhere to be found. I didnt even notice at first until I went to use them later. I started to open the one and it dawned on me. Kind of annoyed because the only reason I bought the set was that it supposedly included both Bio-Carb and Zeolite which isnt easy to find in 1 order. I should probably make my own filter, anyway. As far as quality and effectiveness, theyre totally good.

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.

Easy to install

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