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

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

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

Really like it

Everything was fabulous

It’s a great deal

These are perfect for my small fish tank at work that I have about six Fish keeps it clean for approximately six weeks

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.

As described

Good Item

Exactly what I needed! Good value.
