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

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

Really like it

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

Worked as expected.

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!!

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

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

Really love this filter for my betta on my 5.5 tank. Runs very silent!

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.

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