Marina Slim Filter: Carbon Plus Ceramic & Zeolite Plus Ceramic Cartridges - (Pack of 3 each) Review

This is the first time we have used these filters and if they didn't work we would give the fish away and be done with an aquarium the filters work as if by magic!

I remember when you had to rinse out and measure out those nasty little bits of charcoal, fluff up and place the angel hair material and put your hand in the tank to collect it all again. Especially compared to these stones. A 5 year old could do that. I will never, ever buy a system that doesn't have this level of practicality. grab her you will like them. so will your fish.

As you can see in the picture I received 3 packs of Bio-Carb cartridges with zeolite which was nowhere to be found. I didn't even notice it at first until I used them later. I started opening one and it dawned on me. A bit upset because I only bought the kit because it said it contained both bio-carb and zeolite, which aren't easy to find in the same order. In any case, I should probably make my own filter. They are absolutely fine in terms of quality and efficiency.
