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

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

My local fish store was selling one pack of 3 for $12 and I paid two packs of 3 for $6 so I think I won (sad i didn’t support a local business tho)

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

Perfect!!!

Easy to install

Exactly what I needed! Good value.

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

As advertised

Filters dont last long

Kept my tank clean for 2 months without changing the filters
