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

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)

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

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

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

work great

Exactly what I needed! Good value.

Refills for the slim 20 filter, new set up and the 4 filters seem very efficient, fast water clearing and now maintaining a good water quality. Very satisfied. Nice to get an very quick and early delivery. Thanks.

This is the first time weve used these filters and if they were not going to work we were going to give the fish away and be done with the aquarium however the filters work like magic!
