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

As described

Good Item

As advertised

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

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

Kept my tank clean for 2 months without changing the filters

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

Easy to install

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

work great
