I'm always finding ways to reduce my waste and single use items. I absolutely love these! Plus they are super easy to use.
I'm going to add a thin floss sponge to help grab small debris but very please.
Economical way to keep your Marineland filter fresh

Not quite as easy as buying the filters already made but a whole lot cheaper. They're great for putting extra carbon or zeolite in a tank

This is great. Works well. Perfect for the Marineland 350 filter as it has room for an extra filter on each side. I used it for some ammonia neutralizing crystals mixed with carbon.
You need this with mess fish

I bought this because my tank has some very mess fish and it wasn't practical to replace the whole cartiage all the time now I just replace the filter part and the carbon part
Saves money and cheap

Now I don’t have to buy cartridges anymore. Between pond filter about 12 feet long and 2 feet wide more or less and this product, in total spending is about $20.00. I have cartridges for the whole year. Cant go wrong.

I love the fact that I can fill this with my own media. It's a better investment than always buying more and more replacement filters.

There junk, there hard to open and they break easy, I’m sticking to buying the regular cartridges for them
Save hundreds $$$

I use these Refillable cartridges in all my Marineland Hobs and they work great. I never buy the replacement filters. Instead I add pinky filter floss to one and Seachem Matrix to the other. I clean them as if they were filter cartridges but these versatile cartridges can be filled with anything from mechanical, biological or chemical filtration.

This is easy to fill easy to clean and fast to clean and use and a great way to save money.
