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

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!!

Perfect!!!

Really like it

work great

As advertised

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 was exactly what I needed!

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

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)

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