Marina i25 replacement Power Cartridge is made specifically to fit inside the Marina i25 internal filter. Its unique design allows the water to enter through the center of the cartridge. Split into 2 different chambers, the water 1st enters the zeolite chamber so toxic ammonia is removed. It then enters the activated carbon chamber so all pollutants and odours get removed. The water lastly enters the floss layer where debris gets trapped inside the cartridge. This unique flow of water results in a crystal clear water. For best results, replace every 4 weeks.

Same quality as the big pet store chains but way better on the prices!!! I think customer satisfaction is more important to Entirely Pets too. Very happy with all of my orders!!!

Fish Tank Filter by JF06/02/2012

The Marina i25 filter works well and keeps our small tank very clean. We recommend it for price and efficiency.

Great Filters! by PattiS from AZ03/18/2012

These are the best filters and very easy to change.

Can't beat Entirely Pets' price! by Dorothy from Maryland08/28/2013

There's not much to say about a replacement filter cartridge for a small fish tank. It's a brand name and a fitted cartridge. What I CAN say is this item is far, far less expensive here than anywhere else I looked!

Easy! by Gerry B07/02/2013

This filter does an excellent job of keeping my tank crystal clear. Simple to use slide the old one out, slip the new one in. Fast and easy!

I love this product! by Peeboo888 from Las Vegas, NV06/24/2012

These replacement cartridges are for Marina i25 internal filters. I have a 2.5 gallon tank for my betta fish and use this filter to keep the tank clean. It works so well! Within a few minutes of putting a new cartridge in, the yellowing water was crystal clear. I have had many betta fish over the years and always used this product with them. Great products like this make my bettas very happy!
