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

Easy to install

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

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

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

I remember when you had to rinse and measure out nasty little bits of charcoal, fluff out and place the angel hair stuff and stick your hand into the tank to put it all together again. Especially compared that that, these rock. A 5-year old could do these. I will never, ever buy a system that doesnt have this sort of practicality built-in. Get them. You will like them..... so will your fish.

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

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.

As described

Exactly what I needed! Good value.

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!!
