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

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!

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.

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)

We have an unorthodox fresh water tank for our beta and mud turtle and these filters work amazing at fighting all the blue algae from the tons of natural light we have in our house!!

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

Really like it

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

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

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.

This was exactly what I needed!
