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

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.

Easy to install

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!
