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

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!!

I've 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.

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 doesn't 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.

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.

Super crystal clear water when I use one of each. Never have any issues with the water quality in my fish tank.

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

I have no issues with the filter.

Tetra filters way better

These filters work really well! I love the fact that you can get both types together for a great price!
